Question

Given that f(x) = x2 – 7x – 1, g(x) = 2x – 3, and h(x) = 4x – 5 find each function.

Answer 1

Answer:

A)

Step-by-step explanation:

(f+g)(x) = f(x) + g(x)

now plug in the expressions of f(x) and g(x) :

(f+g)(x) = $x^{2} -7x-1 + 2x-3$

we combine like terms we get :

(f+g)(x) = $x^{2} -7x+2x -1-3$

we simplify we get :

(f+g)(x)=$x^{2} -5x-4$

so the answer is A)
