By the Fundamental Theorem of Calculus, ∫_0^2 (3x² + 2x) dx equals:
A$12$ (using F(x) = x³ + x²)
B$6$ (only first term, missing)
C$14$ (incorrect anti-derivative)
D$10$ (missing constant)
Answer & Solution
Correct answer: A. $12$ (using F(x) = x³ + x²)
F(x) = x³ + x². F(2) − F(0) = (8 + 4) − 0 = 12. Always evaluate at upper limit minus lower.
