Question

How to find inverse fuctions?

Answer 1

If your equation is f(x) = 3x + 2 (or y = 3x + 2), you find the inverse of the function by switching the x and y. So the inverse of this function would be:

x = 3y + 2

Now move the terms around to put it in proper form:

y = (x-2) / 3

Sometimes you can refer to the inverse of f(x) as "g(x)".

So if f(x) = 3x+2, the inverse of f(x) is g(x), where g(x) = (x-2) / 3

Answer 2

Also, when you graph both functions you should have symmetry with y=x
