## College Algebra (10th Edition)

Since the given interval involves open and close parentheses, the lower and upper limits are not included in the set. Thus, the given interval includes the numbers between $-3$ and $-2$, but not $-3$ nor $-2$. Therefore, the given interval is equivalent to: $-3 \lt x \lt -2$ To graph this on a number line, plot hollow dots (or holes) at $-3$ and $-2$, then shade the region between them. (Refer to the attached image in the answer part above.)
