Please help with the first question....

Answer 1

A) The functions are not inverses of each other.

Explanation:

`f(g(x))=√((x^2+3)-3)=√(x^2)=|x|\\e x`

The result of f(g(x)) is not always x, so the functions are not inverses of each other.

In general, a quadratic (or any even-degree polynomial) such as g(x) cannot have an inverse function because it does not pass the horizontal line test.
