ANSWER
First choice
EXPLANATION
The graph of f(x) and
[tex] {f}^{ - 1} (x)[/tex]
are symmetric about the line y=x.
This means that the graph of
[tex]{f}^{ - 1} (x)[/tex]
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.
