Question

If f(x) = 2x-5 and g(x) = x2 - 4x - 8, find (f+ g)(x).

Answer 1

Answer:A

Step-by-step explanation: (2x-5 + x^2 -4x-8)

(X^2+2x-4x-2-3).=x^2-2x-13

Answer 2

Answer:

A. (f+g)(x)= $x^{2}$-2x-13

Step-by-step explanation:

Add f(x) and g(x)

= (2x-5)+($x^{2}$-4x-8)

Add like terms.

=$x^{2}$-2x-13

(f+g)(x)= $x^{2}$-2x-13
