## College Algebra (10th Edition)

The value of $x$ is between 4 and 6, including 4 but not 6. Since the lower limit 4 is included in the set, an open bracket will be used. The upper limit 6 is not included in the set, so a close parenthesis will be used. Thus, the interval notation equivalent of the given inequality is: $[4, 6)$ To graph this interval on a number line, plot a solid dot at 4 and a hollow dot (or hole) at 6. Then, shade the region between them. Refer to the attached image in the answer part above for the graph.
