Answer:
(-4,-2) U (-2,4]
Step-by-step explanation:
Domain is the set of x values for which the function is defined.
We look at the x values on the graph
the graph starts at -4 and we have a hole at x=-4
For a hole we use parenthesis
Graph starts at -4 and ends at -2. Both -4 and -2 have hole, so we use parenthesis.
So interval is (-4,-2)
From -2 to 4 , there is no hole or break in between. the graph is continuous from -2 to 4
so interval is (-2, 4]
combine both intervals
(-4,-2) U (-2,4]
