Question

f^-1(x)

Answer 1

it just says find f^-1(x). This stuff confuses me

Answer 2

Is there a graph, or table?

Answer 3

it says f(x)=3x. i didn't see it before, but i still don't get it

Answer 4

f(f^-1(x))=f^-1(f(x))=x
to find the inverse of a function f(x), replace f(x) with x and x with f^-1(x)
so f(x)=3x becomes x=3f^-1(x), thus f^-1(x)=x/3

Answer 5

so my answer is just x/3 ?

Answer 6

yup :)

Answer 7

Also, I believe that you may simply take the inverse of it; any x value would be put in the denominator, which, in turn, you see the pattern of the new graph would be 1/3x.
