Question

On what interval/s is the graph decreasing?

Answer 1

-1 < x < 1/3

Explanation:

When the graph is decreasing, it means the the graph's slope is negative, or the graph is going towards negative infinity.

We see from the graph that it starts to decrease from -1 to 1/3. Therefore, our answer is -1 < x < 1/3.

Everywhere else on the graph is increasing.
