## Calculus with Applications (10th Edition)

The interval notation of the given expression is: $[1, 2)$. Refer to the image below for the graph.
The inequality includes all numbers that are greater than or equal to 1 and less than 2. Thus, the interval notation of the given expression is: $[1, 2)$. To graph the inequality, plot a solid dot at $x=1$ and a hole (hollow dot) at $x=2$, then shade the region between them. (refer to the attached image in the answer part above)
