Question

use the graph to determine the behavior of the function

Explanation:

Step1: Analyze the behavior of the function between points A and B

Between points A and B, the function is constant as the y - value does not change while the x - value changes.

Step2: Analyze the behavior of the function between points B and C

Between points B and C, as x increases, y decreases. So the function is decreasing.

Step3: Analyze the behavior of the function between points C and D

Between points C and D, as x increases, y increases. So the function is increasing.

Answer:

A and B: constant; B and C: decreasing; C and D: increasing.
