use the graph of the function. determine over what interval(s) the function is positive or…

Explanation:

Step1: Identify x - axis intersections

Find where the graph crosses the x - axis. These are the key points to divide the intervals.

Step2: Analyze intervals above and below x - axis

For intervals where the graph is above the x - axis, the function is positive. For intervals where the graph is below the x - axis, the function is negative.

Answer:

Without seeing the actual graph, we cannot give specific intervals. But the general process is to identify the x - values of the x - intercepts. If the x - intercepts are (x = a) and (x = b) ((a<b)), and the graph is above the x - axis for (x\in(a,b)), then the positive interval is ((a,b)) and if it is below for (x\in(-\infty,a)\cup(b,\infty)), those are the negative intervals.
