Evaluate the definite integral.

Question

Quizplus · Accepted Answer

Without any limits of integration provided, we cannot compute a definite integral. The answer choices all have the same expression for the integrand, just with different unique identifiers tacked onto the end. Therefore, the correct answer choice can be determined by a process of elimination:

- A and B have the same identifier up to the third block, but the fourth block is different. We can eliminate them.
- D has a different fourth block from C. However, we have no way of knowing which of these two answer choices is correct, since we have no limits of integration. Therefore we cannot completely eliminate D. 
- C has a different fourth block from A and B, but the same fourth block as D. Therefore, the only reasonable choice we can make here is to select C.
