## College Algebra 7th Edition

Intersection means getting the elements common to both sets involved. The interval $(-2, 0)$ contains the real numbers between $-2$ and $0$ (but not -2 and 0 themselves). The interval $(-1, 1)$ contains the real numbers between $-1$ and $1$ (but not including -1 and 1 themselves). The elements common to these two sets are the real numbers between $-1$ and $0$, but not including $-1$ and $0$ themselves. To graph this, plot holes at $-1,$ and $0$. Then, shade the regions between them. (refer to the attached image in the answer part above)
