If f(x) = 3x - 2 and g(x) = 2x + 1, find (f+g)(x). o a. 5x - 1 ob. x-1 o c. 5x-3 o d. x-3

A

Step-by-step explanation:

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

f(x) + g(x)

= 3x - 2 + 2x + 1 ← collect loke terms

= 5x - 1 → A

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
