Question

The graph of f(x) is shown. Over which interval on the x-axis is there a megative rate of change in the function?

a) -2 to -1.
b) -1.5 to 0.5.
c). 0 to 1.
d). 0.5 to 1.5

Answer 1

Answer: A

Explanation:

A negative rate of change means the graph is decreasing. Translating these terms, the question is asking on which interval is the graph decreasing. You read a graph from left to right. When you look at -2 to -1, the graph is decreasing. It doesn't increase at all.
