Find the intervals over which the function is increasing. I think it's B which is (-oo,-1),(-1,0) but want to make sure

that looks correct. If your graph let's you scroll upward, double check to see if the line crosses 1 on the x axis. as long as it never touches x=1, you answer is correct

A function is increasing in some given interval if in that interval, reading from left to right, we can see that the graph of the function goes upwards.

We will see that the intervals where the function is increasing are (-∞, -1) and (-1, 0).

Here we need to look at the graph to see this, as we look in the graph, we can see that:

In the interval (-∞, -1) the function goes up.
In the interval (-1, 0) the function goes up
In the interval (0, 1) the function goes down.
In the interval (1, ∞) the function goes down.

Thus, the intervals where the function is increasing are (-∞, -1) and (-1, 0).
