Question

F(x) = x + 7
and
g(x) = x2
What is g( f(-9))

Answer 1

4

Explanation:

Answer 2

g(f(-9))=4

Explanation:

This is a composite function so we need to first find the value of the function on the inside in order find the value of the composite function

f(-9)=x+7=-9+7=-2

we can put -2 instead of f(-9) in the composite function

g(-2)=(-2)^2=4
