Question

Write interval notation.
-$\{x \mid x>-7\}$
A) $(-\infty,-7]$
B) $(-7, \infty)$
C) $(-\infty,-7)$
D) $[-7, \infty)$

Quizplus · Accepted Answer

The notation $\{x \mid x>-7\}$ describes all real numbers greater than -7 but not including -7 itself. The correct interval notation for this is $(-7, \infty)$, which includes all numbers greater than -7 up to infinity but does not include -7 itself.
