$(-3, 2)$ Refer to the graph below.

Work Step by Step

Recall: The intersection of sets $A$ and $B$, denoted by $A \cap B$, is the set that contains all the elements that are common to both $A$ and $B$. The graph shows that the numbers common to the two sets are the numbers between $-3$ and $2$. Thus, the intersection is $(-3, 2)$. Graph this set by plotting holes (hollow dots) at $-3$ and $2$, then shade the region in between. Refer to the graph above.
