Answer: ASet 2: Polynomial Functions (Intermediate)
Explanation
PROBLEM
If f(x) = 3x squared + 2x + 4, find f(2).
If f(x) = 3x squared + 2x + 4, find f(2).
A.✓ Correct
20
B.
21
C.
22
D.
40
Detailed Explanation
Choice A is the best answer. f(2) = 3(2) squared + 2(2) + 4 = 20
Why others are wrong:
B: 21 is incorrect because it does not satisfy the equation.
C: 22 is incorrect because it does not satisfy the equation.
D: 40 is incorrect because it does not satisfy the equation.
