Answer: points of intersection.
- A points of intersection
- B their entire domain
- C their whole range
- D their common tangent
Correct answer: A. points of intersection
Explanation: The limits are the x-values where the two curves intersect.
The definite integral ∫ₐᵇf(x)dx computes the exact area of the shaded region bounded by the curve, the x-axis, and the vertical lines x=a and x=b - the same idea behind the Riemann sum, but evaluated exactly rather than approximated by rectangles.
Concept context
Using definite integrals to compute the area under a curve, the area between two curves, and the areas enclosed by standard curves like circles, parabolas, and ellipses.
