^ sorry didn't finish: show that k(x)= k(1/x)

yea i realize that but the question says "show" that they equal each other. im thinking possibly by some sort of identity or something.

ohh i see duh!! lol thanks =)

im sorry, i wrote the question wrong, its supposed to be: f(x)=(-3/x^2), but i think i can follow this same format to solve this one too right?

okay thanks i get it (:

i just need the help oof i suck at math and have to do edgenuity and finally got from 40 something to 67
