Geometrically, the integral of f from a to b measures:
ASlope of the curve at b
BArc length from a to b
CArea between curve and x-axis
DMean of f at a and b
Answer & Solution
Correct answer: C. Area between curve and x-axis
For nonnegative f it is the area bounded by the curve, the x-axis and the lines x = a and x = b.
