BRAINLIESTT ASAP! PLEASE HELP ME :)

Answer 1

Answer:

20  

Step-by-step explanation:

ƒ(x) = 3x² – 2

g(x) = 4x + 2

1. Add the functions

By definition,  

(ƒ + g)(x) = ƒ(x) + g(x)

3x²          - 2

      + 4x + 2

3x² + 4x

(ƒ + g)(x) = 3x² + 4x

2. Evaluate (ƒ + g)(2)

(ƒ + g)(2) = 3(2)² + 4(2) = 3(4) + 8 = 12 + 8 = 20

Answer 2

Answer:

$\displaystyle 20 = (f + g)(2)$

Step-by-step explanation:

$\displaystyle [4(2) + 2] + [3(2)^2 - 2] = [8 + 2] + [3(4) - 2] = 10 + [12 - 2] = 10 + 10 = 20$

I am joyous to assist you anytime.
