## College Algebra (10th Edition)

The given interval involves a close bracket. This means that the upper limit (which is 2) is included in the set. The given interval is unbounded on the left. Therefore, the given interval is equivalent to: $x \le 2$ To graph this on a number line, plot a solid dot at 2, then shade the region to its left. (Refer to the attached image in the answer part above.)
