a. 3x2 + x-1
b. 3x-2
c. 3x2+x+1
o
d. 4x2 +1

C

Step-by-step explanation:

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

f(x) + g(x) = 3x² - 1 + x + 2 = 3x² + x + 1 → C

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
