College Algebra 7th Edition

$2 \le x \lt 8$ Refer to the image below for the graph.
A bracket on the left means 2 is included in the set. A parenthesis on the right means 8 is not included in the set. Thus, the equivalent inequality of the given interval is: $2 \le x \lt 8$ To graph the interval on a number line, plot a solid dot at $2$ and plot a hole (hollow dot) at $8$. Then, shade the region between them. (refer to the attached image in the answer part above)
