Question

If f(x) = 3x + 2, find f(2).
a. 2
b. 5
c. 8
d. 9
e. 12

Answer 1

3(2)=6, 6+2=8 the answer is C

Answer 2

C

Explanation:

Since the number in the parenthesis is treated as "x", for f(2), replace "x" with 2. So the equation will be f(2) = 3(2) + 2. Then multiply. f(2) = 6 + 2. Lastly add them up. f(2) = 8. The answer is 8.
