If f(x)=5x^3-2 and g(x)=2x1, find (f+g)(x).

Note: your g(x) function is a little bit unclear. Thus, I am assuming that

g(x) = 2x-1

Anyway, the procedure remains the same. It would anyways clear your concpet.

(f+g)(x) = 5x³ + 2x - 3

Step-by-step explanation:

Given

f(x) = 5x³ - 2

g(x) = 2x - 1

To determine

(f+g)(x) = ?

Using the formula expression

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

           = 5x³ - 2 + 2x - 1

           =  5x³ + 2x - 3

Therefore, we conclude that:

(f+g)(x) = 5x³ + 2x - 3
