Question

1.) f(x) = x +1 g(x) =- 2x + 5 Find f g(2)

Answer 1

Answer:

2

Step-by-step explanation:

Given f(x) = x + 1 and g(x) = -2x + 5, find f(g(2)).

First, we must plug in the value of g(x) into f(x).

f(g(x)) = (-2x+5) + 1

Then, we plug in g(x)'s x-value.

f(g(2)) = (-2(2) + 5) + 1

Now, we solve.

f(g(2)) = (-4 + 5) + 1

f(g(2)) = 1 + 1

f(g(2)) = 2
