#### Answer

$-3 \lt x \lt 0$

#### Work Step by Step

Having parentheses on both ends (left and right) mean that the numbers -3 and 0 are not included in the set. Thus, the equivalent inequality of the given interval is: $-3 \lt x \lt 0$ To graph the interval on a number line, plot holes (or hollow dots) at $-3$ and $0$, then shade the region between them. (refer to the attached image in the answer part above)
