#### Answer

Refer to the image below for the graph.

#### Work Step by Step

The interval $[-4, 6)$ contains the real numbers between $-4$ and $6$, including $-4$ itself but not 6. The interval $[0, 8)$ contains the real numbers between $0$ and $8$ (including 0 itself but not and 8). Union means combining the elements common of the two sets involved. Combining the elements of the two given sets will include the real numbers between $-4$ and $6$ and the numbers between $6$ and $8$, including $-4$ itself but not 6 and 8. To graph this, plot a point at $-4$ and holes at $6$ and $8$ Then, shade the regions between them. (refer to the attached image in the answer part above)
