College Algebra (10th Edition)

The given interval involves an open bracket. This means that the lower limit (which is 0) is included in the set. A close parentheses was used, so the upper limit (which is 1) is not included in the set. Thus, the given interval includes the numbers between $0$ and $1$ and includes 0 but not 1. Therefore, the given interval is equivalent to: $0 \le x \lt 1$ To graph this on a number line, plot a solid dot at 0 and a hollow dot (or a hole) at $1$. Then, shade the region between them. (Refer to the attached image in the answer part above.)
