I'm old - I'm relearning this to teach my child who's in Algebra 2 Honors. You are SO much better than my kid's teacher. Her go-to is "You're in honors, you should know this." Anyway, thank you - you really have a gift for making what could be a complex topic so easy to understand.
I just wanted to say thanks so much! I'm 40 and going back to school, haven't done any math besides basics in 20yrs. I found other channels but they were way to much, couldn't follow, getting very discouraged. Yours are much better suited for me. Sincere thank you!
Awesome video! All of your learning videos in your collection provide the best explanations showing step-by-step examples of any other RUclips page. Thank You!
how do you decide whether you'll allot x or y the larger number when youre coming up with the co ordinates? like in 16:34 you put the bigger values under x and smaller ones under y whereas in 18:20 you put the bigger values under y and smaller ones under x.
Great question! If there is no horizontal shift, a reflection over the y-axis actually has no change on how the graph looks. y = |x| is essentially the same as y = |-x| since you can simplify |-x| to |x| If there is a horizontal shift you need to be more careful... For example, y = |-x - 4| -Factor out -1: y = |-1(x + 4)| -Simplify: y = |x + 4| so y = |-x - 4| is essentially the same as y = |x + 4| Hope that helps!
I wouldn't classify the negative in the front as the "a" or "k" value. If the negative is being multiplied to the function, it will always represent a reflection over the x-axis. I wouldn't call that an "a" value because it is not technically a vertical stretch or shrink. Remember, the "a" value is always considered to be positive, so if you see a negative, it is a reflection "k" values are always added or subtracted from the function (so never multiplied). If you look at example C, k = 7 because of the +7 Hope this helps!
Ok I just clicked the time stamp to see where 14:30 was in the vid cause I got a notification about a reply. And the ad that started playing was "what? Still using RUclips videos for math help?"
@@l34hu I am so happy to hear that! I know remote learning is difficult but stick with it :) And just FYI, I have playlists for Algebra 2 and Precalculus set, so that may help you to find the right video. Have a great day!

Does this teacher happen to be Mrs. Sanders from munford

Thank you for all your kind words!
i actually understand whats happening😭, thank you so much
You are saving my life. Thank you. I got an Algebra 1 quiz to tomorrow and I was so nervous.
Hope you did well on your Quiz! Thank you for your kind words!!
I got a D+. Not very happy about it. But at the end of the day, school is for learning and mistakes happen. Thank you.
@@marcopon6978maybe cuz you watched a algebra 2 video for algebra 1
this has been the simplest breakdown thank you so much

You are a star! Thank you mom
@LeafGod yes
Thank you so much madam. Love from Bangladesh. May god bless you and your family more.
Wow! Thank you so much!
Thank you for the great video. Better explained than any other source available
Thanks so much for watching!
Good explaination
this is the best explanation... Thanks a lot 😊
1:19 Are you sure? We have horizontal stretch if 0
no, you are right.
Thank you for the great video!
Thank you for watching!
How about horizontal translation of a 5th degree and not factorable polynomial in it's expanded form. How do we calculate the new coefficients?
BEST VIDEO EVER.
Thank you for watching!
17:10 The horizontal stretch is by a factor of two. I though if you have you had -1/2x within the radical you would divide by 2 all the x values.
Yes she is wrong, it is horizontal stretch by reciproc of 1/2 (2), and not vertical stretch!
anyone know y=x^2 and y=-x^2+4, i thought when we reverse the sign of x it reflects in y-axis , but why this graph is reflecting in x-axis?
Thank you this was very helpful Mrs. GA!
Thank you for watching!
thank you I can stay healthy now
Glad you found the video helpful. Thanks for watching!

you know what nvm i just figured it out.. im kinda dumb thats all
do u hate gay people
2024? 😂
8:40 Hi! for an absolute value function, what would the equation look like if it was a reflection about the y-axis?
Great question! If there is no horizontal shift, a reflection over the y-axis actually has no change on how the graph looks.
y = |x| is essentially the same as y = |-x| since you can simplify |-x| to |x|
If there is a horizontal shift you need to be more careful... For example, y = |-x - 4|
-Factor out -1: y = |-1(x + 4)|
-Simplify: y = |x + 4|
so y = |-x - 4| is essentially the same as y = |x + 4|
Hope that helps!

Hi I'm a little confused on how to tell whether the negative at the start function is a the "a" or "k" value 4:47
I wouldn't classify the negative in the front as the "a" or "k" value. If the negative is being multiplied to the function, it will always represent a reflection over the x-axis. I wouldn't call that an "a" value because it is not technically a vertical stretch or shrink. Remember, the "a" value is always considered to be positive, so if you see a negative, it is a reflection
"k" values are always added or subtracted from the function (so never multiplied). If you look at example C, k = 7 because of the +7
Hope this helps!
MathWithMrsGA alright great!!! thank you so much for explaining this! Great help for my test on friday 👍
I clicked on the video a nd im at 14:30 already for some reason
look at the link it probably says "&t=870s" after the whole thing
its cuz ur gay
@@hpomen9681 I probably was on mobile and it wasn't a link I clicked.
@@jensmalzer6344 also are u ok? Do u have something going on in ur life u need to talk about?

is this for algebra 2?
This video was originally made for my Precalculus class, but the concepts are covered in Algebra 2 as well :)
MathWithMrsGA thank you ms! learning math through zoom is not working for me and your videos are really helping me
