Question

10 points which of the following describes the graph ? Help Needed

Answer 1

ANSWER

First choice

EXPLANATION

The graph of f(x) and

${f}^{ - 1} (x)$

are symmetric about the line y=x.

This means that the graph of

${f}^{ - 1} (x)$

is the reflection of f(x) in the line y=x.

This explains why the composition of a function and its inverse yields x, as the result.

The first choice is correct.
