OMG...my teacher made this appear to be like rocket science, this guy is FANTASTIC! Thank goodness for you tube and people who can really explain a process.
It is positive because once you change that first x value (x^6) into -x then the negatives cancel out because it has an even root. Other than that, everything else is positive as well. Hope that helped.
f(x)=sqrt(x) f(-x)=sqrt(-x) Since sqrt(-x) doesn't equal sqrt(x), f(x) is not even. Since sqrt(-x) doesn't equal -sqrt(x), f(x) is not odd. Thus, f(x)=sqrt(x) is neither.
honestly im an advanced student and nobody simply told me 'plug -x in, if its the same thing it was, its even. if its the opposite of what it was, it's odd. if it doesnt match either, it's neither. a very easy concept commonly made difficult.
I'm attempting to determine whether or not the square root of x is even, odd or neither. I am assuming that since the square root of x looks like x½. and since there cannot be a negative under the radical it is an even function? Please confirm or deny if possible
@kristijanadrian For the common student learning pre-calculus, neither is a valid answer. You may be correct, but that won't help you with doing a test for a pre-calculus teacher.
Depends on your proffesion. 75% of well-earning and usefull-to-society proffesions will use this. ofc, if you will be a window's cleaner, you will not.
question for number 3:... the second to last equation you wrote out = -x^3 + 2x^2 -1.......... wouldnt that 2x^2 be a negative??? Correct me if I am wrong. I need to understand why it is positive.
wait for example 3) how did u get from (-3)[in the power of]2 + 2(-x)[in the power of]2 - 1 ---> -x[in the power of]3 +2x[in the power of]2 -1 ... isnt it supposed to be -x[in the power of]3 + -2x[in the power of]2 - 1 ??
The reason 2x^2 is positive is due to BEDMAS, the exponent -x^2 becomes positive and then all one has to do is put the 2 in front of the question, resulting in a positive 2x^2.
omg thank you i finally understand how to do this
Beautiful, this short 5 minute video is straightforward unlike the rest of the videos. Thank you.
This video is only about 6 minutes long and it helped me more than my professor could in 40 minutes.Thank you so much!
What a great video you have out together!. Thank you for taking the time to explain this in such a clear way =)
OMG...my teacher made this appear to be like rocket science, this guy is FANTASTIC! Thank goodness for you tube and people who can really explain a process.
Dude.... thank you so much. You are so much better at explaining this stuff than any of the T.A.'s at my school.
jesus christ that was easy, cheers dude :)
You're the real MVP
Thankyou soooo veryyyy much. This saved me in my finals. I was struggling with this before I saw your video. Thanks again.
:-)
This was so helpful!! Thanks for the video.
Good Video... I have a test in 30 minutes and wasnt too clear about even, odd functions and this helps greatly!
Thankkk youuu, I saw it after 15 years❤
You're welcome. Study well.
Sir u are a great teacher and help students out when their own teachers cant teach.
thank you man, you're a life saver!
I paid $190 for a textbook that made this super confusing. My goodness, youtube is amazing. Thank you!
Thnx for the video ...I really learned the process of determine even or odd function with only one view... Excellent teacher!
This video helped me understand much better! Thank you for your help! math test is monday. thanks once again.
9 years later and still helpful
Thank you man!! The explanation was great!#
This is amazing. Thank you. I am so tired of math teachers making everything so much harder than it needs to be. Thank you for making it easier.
i have a test on all this and you explained it a heck of a lot easier than my teacher :) thank you!
what would i do without online math youtube tutors. Thank you good sir!
thanks you so so so very much. you have shaved like 2 hours off my study time, and probably helped me get an A on this test :)
Thank you my man, you saved me bout couple hours worth of struggle
yes sir this helped a lot. my teacher took a day explaining this, i didnt get it. and now i got it in 5 min just by watching your video.
Thank you so much!!!! This what such a clear explanation
Thanks a lot dude. it seems like im actually learning more on youtube than i do in lectures
Thanks from Kazakhstan!
You should totally make your username Randerson. First thing I thought of.
Then I got a lot of help, thanks for the vid!
What happen to example 2
3(-x)^2 =3x^2?
Is it not -3x^2?
naaah , square of any variable is positive only
even if it is in negative or positive
Thank you it's so easy now
thanx alot....U just made my maths life easier.
You make it easy dude THANK YOU!!!!!!!! :) :) :D
Thank you so much! VERY helpful & easy to understand!
Great video! Big help for my exam
This video REALLY REALLY helped me... Thank you!!
You are the best. Thanks lots
wow, thanks!! that really helped. :D
Thanks Man i realy appretiate it
great thanks alot very clear and practical and understandable
It is positive because once you change that first x value (x^6) into -x then the negatives cancel out because it has an even root. Other than that, everything else is positive as well. Hope that helped.
damn finally a person that can explain this well!!!! jeeeez.... thnx a lot sir
THANK YOU!!
Great teacher!
Thank you lifesaver! Same with other people. my teacher isn't very good at explaining....
Fantastic very well explained
Thank you! def helps!
Funny how this 5 minute video explains this concept more clearly than a one hour lecture, Thanks a bunch man.
f(x)=sqrt(x)
f(-x)=sqrt(-x)
Since sqrt(-x) doesn't equal sqrt(x), f(x) is not even.
Since sqrt(-x) doesn't equal -sqrt(x), f(x) is not odd.
Thus, f(x)=sqrt(x) is neither.
i need this for our prject. :D thanks !
Thank you so much! Wish you were our video class teacher in BJU or A Beka! :)
thank you for explaining this, it really helped! and it was very easy to understand! :D
CLAP CLAP WELL DONE!!! I SEE THE LIGHT THANK YOU SIR
Be careful. (-x)^2 means (-x)(-x) which goes to just x^2. Thus, we get 2x^2 for the middle term.
Extremely helpful.
thanks! this helped so much
You're welcome. Study well.
honestly im an advanced student and nobody simply told me 'plug -x in, if its the same thing it was, its even. if its the opposite of what it was, it's odd. if it doesnt match either, it's neither. a very easy concept commonly made difficult.
Great video. It would have been nice to see the graphs of even and odd functions though
great explanation!! thank you very much. keep up!!
holy cow this was easier than I thought. My teacher made it seem very hard =/
Great explanation.. Thank you so much!
what do you do when their is no negative to factor out of the f of x when looking for negative f of x
I'm attempting to determine whether or not the square root of x is even, odd or neither. I am assuming that since the square root of x looks like x½. and since there cannot be a negative under the radical it is an even function? Please confirm or deny if possible
great stuff very helpful
if only i had found this before the test :P
@kristijanadrian For the common student learning pre-calculus, neither is a valid answer. You may be correct, but that won't help you with doing a test for a pre-calculus teacher.
HOLY BALLS. Thank you. My teacher sucks.
How can you determine algebraically if the function is symmetrical across a certain line, eg. x=2?
Thank you, very helpful:)
Thank you this really helped
Has anyone ever told you you sound EXACTLY like Casey Affleck? P.S. Great video.
Infinite thanks !!!
helps a lot! thanks!
why math is hard ?
are we going to use this in our real life ?
Depends on your proffesion. 75% of well-earning and usefull-to-society proffesions will use this. ofc, if you will be a window's cleaner, you will not.
yeah thanks very much
lies
no not that. I was saying thanks to the guy for explaining this.
Markas Černiauskas hahahah answer is on point
thanks:)

And they say you have to get use to prof and there ability to speak english thanks man :P
you're gold dude
thank you so much!!!!!!!!!!!!!!!!!
Thanks man
You're welcome.
YOU ARE MY SAVIOR. THANK YOU! :)
Thank you!
Thanks for your help full video
Thank you so much
Thank you so much ❤️❤️❤️
this helped me
thanks a lot
;)
THANK YOU VERY VERY MUCH :)

THANK YOU SO MUCH
Thank you sir!!!
thank you man!
Fnx a lot! Realy helped
Thank you soo much :)
where did those x came from :(
Thanks man!
Excuse me but isn't 2(-x) is -2x why did you write it as positive like this 2(-x) is +2x
First Queen subtracting a negative gives a positive
THANKS A LOT
Thank you!!!!!!!!!!!
