The other kind is taken over a closed interval where the function has an infinite:
AEndless series
BDiscontinuity
CSteep slope
DEndless sum
Answer & Solution
Correct answer: B. Discontinuity
1. The integrand blows up somewhere inside.
2. The interval itself is finite.
3. It is a discontinuity there.
