Question

What is the inverse of the function f(x)=1/3x-2

Answer 1

To find the inverse of a function you switch the x and y terms.

First you want to rewrite it in terms of x and y. y=1/3x-2

Then switch x and y. x=1/3y-2

Then solve for y. x+2=1/3y
3x+6=y

Then rewrite as a function using correct notation f^-1(x)=3x+6
