alleryThe AREA bounded by y = x² and the x-axis from x = 0 to x = 3 is:
A$3$ (using only the upper limit)
B$6$ (twice the upper limit value)
C$9$ (using anti-derivative properly)
D$27$ (cubing the upper limit)
Answer & Solution
Correct answer: C. $9$ (using anti-derivative properly)
Area = ∫_0^3 x² dx = [x³/3] from 0 to 3 = 27/3 − 0 = 9.
