Here we want to see in which intervals the given function is positive, the answer is:
(-4, 0) and (6, 8]
So the function is positive if and only if the graph of the function is above the horizontal axis.
With this criterion, we can see that from x = -4 to x = 0 the graph is above the horizontal line, thus, in this interval the function is positive.
The same thing happens from x = 6 to the right (the graph ends at x = 8), here the function is also positive.
Then the two intervals where the function is positive are:
(-4, 0) and (6, 8]
