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.
