Answer:
C
Step-by-step explanation:
First we need to figure out what it means when we say a function is increasing.
Here is a small tip:
As x goes up, the y will go up as well.
In this case, we say the function is increasing.
From the graph we see that the function is increasing from -3 to 3.
so the interval will be [-3, 3]
In this part, when x goes up, y goes up as well.
