Question

Given the definitions of f(x) and g(x) below, find the value of f(g(5)).
N
f(x) = 2x² + 7x + 4
g(2) -x+ 5

Answer 1

Answer:

f(g(5)) = 4

Step-by-step explanation:

It says to find the value of f(g(5)). In this case, we first have to find g(5).

Plug 5 into g(x) = -x+5

g(5) = 0

Now, f(g(5)) is f(0), since g(5) was found out to be 0.

Plug in 0 into 2x² + 7x + 4

2(0)² + 7(0) + 4 = 0 + 0 + 4 = 4

So the answer is 4.
