# Thread: graph of inverse function

1. ## graph of inverse function

http://i29.tinypic.com/zmckki.jpg

the above is the graph of f.

what is the value of f ^-1 (2)?? f^-1 as the inverse of f
What is the value of f ^-1 (0) to the nearest tenth.

$\displaystyle x = f^{-1}(y)$

what is the x-value when y = 2 on the graph?

what is the x-value when y = 0 on the graph?

thanks, but still a little confused...so would the first answer be 0?
the second one is still not registering with me.

the second one is still not registering with me. you have to estimate x ... it's between -1 and -2.
