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.
Answer:
(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
