Unit 1 MCQ AP Precalculus Exam Review (64-129)

The table gives values for a polynomial function h at selected values of x. It is known that h is increasing on the interval 0 < x < 4. Which of the following could be true about the graph of h on the interval 0 < x < 4?

• The graph of h is concave down because the average rate of change over equal-length input-value intervals is increasing.

• The graph of h is concave up because the average rate of change over equal-length input-value intervals is increasing.

• The graph of h is concave down because the average rate of change over equal-length input-value intervals is decreasing.

• The graph of h is concave up because the average rate of change over equal-length input-value intervals is decreasing.
