Answer 1

Hi there.

The answer is A choice.

Step-by-step explanation:

The function decreases when x > 0 and y < 0. Rather say that when x-term keeps increasing, the y-value will decrease which is a decreasing function.

By looking at the graph. We can find the decreasing graph by looking which region does the graph head down when x increases.

And that is when - 3 <= x <= 2 as the graph starts decreasing.
