Question

how would i evaluate f^-1(8)?

Answer 1

lol :)) good question

Answer 2

anyone know how to get c as well?

Answer 3

you would have to find\[f^{-1}(x)\] first

Answer 4

I may not be able to help with your question, but did you know that if you hold down the ALT key while pressing the PrintScreen button, it will place only the active window in the clipboard?

Answer 5

I'm on a mac haha

Answer 6

then how would we find f^-1(x)?

Answer 8

Answer 9

but thanks for the mac tip haha

Answer 10

yea. funny. it works on linux.

Answer 11

Answer 12

\[f(x)=y\]
\[x=f^{-1}(y)\]

Answer 13

so in terms of the graph, the answer is 10?

Answer 14

that's seem to be what the answer would be.

gracias. ty.

Answer 16

Answer 18

ah, I see Unkle's point. find the value of x when f(x) = 8.

Answer 19

so i just need to look at the y value basically.... to find the value of x

Answer 20

yeah i should not have written \[f^{-1}(x)\]
it is a function of y\[f^{-1}(y)\]
