Question

Find the value of f(g(-1).

Answer 1

Answer: -8

Explanation:

`g(-1)=2(-1)+5=3\\\\f(g(-1))=f(3)=1-3^(2)=\boxed{-8}`

Answer 2

b.) f(g(-1)) = -8

Explanation:

Given following:

• f(x) = 1 - x²

• g(x) = 2x + 5

Start solving from the right while doing these sums.

• f(g(-1))

• f(2(-1) + 5)

• f(3)

• 1 - (3)²

• 1 - 9

• -8
