  1. 15
  2. 21
  3. 27
  4. 33

UNANSWERED.

The correct answer is E.

A: The answer is 39. To solve this function problem, plug in the number 3 wherever the b occurs
h(b) = b3 + 3b + 3
Tip: Please read the problem carefully and note the b3 is to the 3rd power and not squared.
h(3) = 33 + 3(3) + 3

      = 39
