Hey there! :)

Answer:

125.

Step-by-step explanation:

When g(x) = -1:

g(-1) = 2(-1) + 7

g(-1) = -2 + 7

g(-1) = 5

Plug this into f(x) since the question is asking for f(g(x)):

f(x) = x³

f(5) = 5³

f(5) = 125.

Answer:

-1

Step-by-step explanation:

f(x) = x^3

g(x) = 2x + 7

f(g(x)] =

Let g(x) = -1

Replace g(x) with -1

f(g(x) = f(-1) = (-1)^3 = -1
