D) $\{ x \mid - 3 \leq x < 7 \}$

Quizplus · Accepted Answer

The interval [-3,7] includes all values of x from -3 to 7, including -3 and 7. This can be written in set-builder notation as $\{ x \mid - 3 \leq x \leq 7 \}$. The corresponding interval notation is [-3,7]. The graph on a number line would include closed circles on -3 and 7, with a solid line in between to represent all real numbers between -3 and 7, inclusive.
