# LO3.2

## Look-fors

I have mastered this learning objective when:

a) I use appropriate notation for inverse functions

b) I understand the relationship - graphical and analytical - between a function and its inverse

c) I can explain the meaning of "inverse function" in plain language

d) I can find the inverse of a function f(x).

e) I can decide whether f(x) and g(x) are inverse functions by verifying that f(g(x)) = x
