Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

I've got an hour before my test and this helps. I mean, I'm doomed, but it does help a little
your name goes well with your comment xD
Same man
@@yoyo8915601 given I don't get notifications for some replies it does help. (Yours included).
Did you pass the test?
@@theultimatenewplayer9341 yep I ended the class with an a-
I appreciate my teacher's effort, but I feel you helped me a lot more than he did. Thank you.
8:58 never TWAT quite touches the y axis. Lmao!
Lmao
Just always remember: Teachers are just temporary, but Khan academy is eternal!
😆
You're an amazing teacher! I wish all teachers would simplify everything as well as you do. Thank you! (:
i stopped school for 4 years, well, basically i skipped WHOLE HIGHSCHOOL due to monetary problems. and now im given a chance to go back, but im old as hell and i dont wanna go back to gradeschool. so with your videos, im gonna try learning everything my batchmates learned in 4 YEARS. in one month.
Bro did u do it?
yo how did it go
I believe you're smart, you can learn "4 years" of high school (and MORE) in no time.
Very informative. Studying for a precalc quiz this morning.
@Adam Franek lmao even if she saw your comment she probably wouldn't remember
Adam Franek lolol asks about a test that was 6 years ago
@@jamesjudge7485 lmaooo
Way better than my teacher
Khan Academy is one of the best things ever
You really should just get my pre-cal teacher's salary because you taught me (and most of my classmates) when he didn't. I can't thank you enough!
THANK YOU KHAN ACADEMY I NOW KNOW I KHHHAAAAN DO THIS!
8:57 "Twat." LOL
I laughed too. XD
thank you for your hardwork khan academy, this has been stressing me out for the past few days.
Yay! I have been looking for thes on your channel and they have finally come! Thank you soooo much
Thanks, that's helpful
Thanks, very good explanation :)
Nicely done! There is a hidden poetry (believe it or not ) to graphing. "Higher than any fireworks finale, longer than any Empire, is the pure flight of the curve seeking Infinity."
Next topic for my students - yr 12s, watch this.
lol 5 to the y-eth power... lol... when you're learning math....the bible version. We in the book of logarithms, chapter 5 verse 1 people... open up ya bibles!!
Sal, you have helped me to gain a real intuition for mathematics.
Thank you (from London).
Khan academy coming in clutch 🙌
How would you graph a natural logarithm function?
for the first time in my life i actually got a bad math teacher and i cant understand anything she tries to explain,this year im relying on this channel so hard xD
Thank you !
Thanks for all those amazing videos! So practical!
Great, you didn't show how to gather any information from it...
"SAL" the best teacher I had see it in my studies life ...
12 minutes before exam clutch thanks man love your organisation
That’s the best
Thank you very much, whoever made this video. Thank you, you have really helped me tonight.
0:33 y'th power! y'th power! Kenny the Klansman was always made fun of for his lisp...
second
awesome!!
Sal Khan really loves dark theme.
Wow. Our maths teacher told us to graph an entirely different inverse function and reverse the x's and y's to get the graph we're looking for... Why didnt I just simply do this as Sal teaches? haha
why X value can't be zero?
whats the range?
Watching this video before my freshman math college exam tomorrow and I came unprepared unknowing that courses end much earlier in college than in high school and with a low grade cause I forgot to do a majority of assignments. Wish me the best of luck for me to not fail this exam as I did with the too-late-to-turn-in homework I had this semester!
Very helpful, when you said something like, y = the power to get to x it all just clicked. Thankx a lot mate.
I thought he said "5 to the White Power" ....
great videos though, thank you! :)
everyone seems to enjoy 8:58
Thank you, you saved me from my monotone and boring teacher's lectures.
first
is this just the same as how you graph an exponential function?
Seth Nino Paparon logarithms are the inverse of exponentials. If you want, you can graph y = 2^x then just switch the x and y coordinates to graph y=log_2 x
neat
I really understood when you said we pick nice exes that give us nice clean answers for why
Pre cal? I'm learning this in Algebra 2 :/
Why are we studying pre- calcuse material when we are in algebra 2 class??
im stuck with this problem and its biting me side ways. It's y=f(x)= log base2 (2-x)-2???? What am I even suppose to do with this. ive been looking for videos on how to graph not only with transformations but with different bases and no one is showing that. its all just base 10 hella annoying. can u help me?
straight up... i love you, no homo
You have a pretty similar voice to "Old Ted Mosby" of How I Met Your Mother but instead of telling us that story you are teaching us math :) Thnx for the video :P
great video but 4:50 is crazy lool
YAYY! Quite simple when someone knows how to teach
Use background and black for writing. That helps well and save time. And looks good. These different colours are causing some unidentified problem while listening. Thx
1. First graph log base2 (x) on a set of axis and then carry out the below transformations.
2. The (2-x) portion - means that it is the graph of log base2 reflected in the y axis.
3. Now, once you do that, the (-2) at the end of the function means that the entire graph is moved down 2 units.
Great maths textbook-
just google, IBID Press Math HL pdf. It is an IB textbook but it is fantastic, download from the first 2 links (which will be from 4shared.com)
Why my teacher went through this faster than the flash and gave us 100 problems to do 🤕. Ty bro bro
well this is very useful video..but what if only graph is given and we are asked to write the equation of the graph? How to analyze it? Do we need to memorize the equations of the corresponding graphs?
I have log5(x+1). I reckon that when 4 is my x value, I get a 1 for my why value, which would be log5(x) translated to the left by one.
Slowly my consciousness is expanding because of this wonderful human being. I am so very, VERY grateful. thank you thank you thank you!
when you have 5 to the y power, 5 to the y power, 5 to the y power, 5 to the y power...
if it gets infinitely closer to the y axis shouldn't there be an asymptote
Nathanael Shin there is one on the y axis, he just didn't mention it.
I haven't learned anything with graphing logs yet, so I looked at the title with so much trepidation, but then.. wow! I get it so easily from watching this! thank you SO much!!!!
I have learned more from this than I have from he time we learned this in class. Thanks
What the hell? This actually made sense. Thanks Mr Academy.
nice video mr khan!
i have a log quiz tomorrow in alg. 2 trig, thank you for this.
Khan you have saved my butt so many times I don't know how to thank you
thank you so much you were very helpful! i wish all teachers explained as good as you did
perfectttttttt
How can i build a graphic of y = Log I -x² -4x +1I base 1/2 ?, im having a really hard time here :/ .
Use a calculator
what do I do if there is a 2 in front of the log?
very informational thank you
-Toby okunna
I lovee u , thank u. so much
This makes it so much simpler.
8:58 he says "Twat" .. haha
Hope the advice helped
thank you sooooo much! you're amazing!
thank you so much!!
OMG, thanks you! XD
Thx a bunch man
bless my exam tmr:
I get it now
Thanks:)
I still don’t get it
still don't get this bs
truly a genius!
helps so much!!
TO THE POWER OF Y!!! For christ's sake, it sounds awful when you're saying 'yth power'
hahaha... you so crazy... this is math church... Prraaaise be to trigonometry. yaaaassss!!
What if there is a coefficient?
infront of the entire logarithm? or infront of the argument?
if its infront of the argument, that means theres a horizontal stretch/compression
if its infront of the entire logarithm, that means theres a vertical stretch/compression
@holumyde1 Looks like you need to be studying grammar not math.
Didn’t ask
