Question

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4, identify (f + g)(x).

Answer 1

(f + g)(x) = x^2 + 3x - 6

Explanation:

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4

Plug in:

(f + g)(x) = x^2 + x − 2 + 2x − 4

(f + g)(x) = x^2 + 3x - 6

Answer 2

x^2+3x-6 is your answer.

Explanation:

It tells you to identify (f+g) so all you do is add them together.
