#### Answer

Refer to the image below for the graph.

#### Work Step by Step

The value of $x$ is greater than or equal to 4. Since the lower limit 4 is included in the set, an open bracket will be used. The inequality is unbounded on the right side, so $+\infty$ will be used. Thus, the interval notation equivalent of the given inequality is: $[4, +\infty)$ To graph this interval on a number line, plot a solid dot at 4. Then, shade the region to its right. Refer to the attached image in the answer part above for the graph.
