What is the question here?

These are composite functions and can be done quite simply, as long as you go step by step.

A. f(g(-3)):

First what is g(-3)? According to the graph g(-3) = 3.

So f(g(-3)) = f(3) = 0

B. f(g(0)):

Again, what is g(0)? According to the graph g(0) = 1.

So f(g(0)) = f(1) = -1.
