D)All of these responses are correct.

Question

Quizplus · Accepted Answer

If a curve has a slope equal to zero at some point A, it means that the tangent line to the curve at point A is horizontal. This implies that to the right of A, the curve can have a positive slope, a negative slope, or be a straight line depending on the behavior of the curve. Therefore, all of the response choices are correct.
