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


(f + g)(x)


options:

A) x2 – 5x – 4

B) x2 – 11x + 4

C) x2 – 3x – 6

D) x2 – 5x – 6

Respuesta :

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) = [tex]x^{2} -7x-1 + 2x-3[/tex]

we combine like terms we get :

(f+g)(x) = [tex]x^{2} -7x+2x -1-3[/tex]

we simplify we get :

(f+g)(x)=[tex]x^{2} -5x-4[/tex]

so the answer is A)

Answer:a
