Q. What inequality represents this interval?\newline(,2](-\infty, -2]\newlineChoices:\newline(A) x<2x < -2\newline(B) x2x \leq -2\newline(C) x>2x > -2\newline(D) x2x \geq -2
  1. Identify Endpoints: Identify the endpoints of the interval and whether they are included in the set. The interval (,2](-\infty, -2] has -\infty as the lower bound and 2-2 as the upper bound. The square bracket at 2-2 indicates that 2-2 is included in the interval.
  2. Determine Inequality: Determine the inequality that corresponds to the interval. Since -\infty is not a number that can be reached, it is not included, and the inequality will not have an equal sign for the lower bound. However, because 2-2 is included, the inequality must have an equal sign for 2-2.
  3. Choose Symbol: Choose the correct inequality symbol. The interval extends from -\infty up to and including 2 -2 , which means the values that x x can take are less than or equal to 2 -2 .
  4. Match Inequality: Match the correct inequality with the given choices. The inequality that represents the interval -\infty, -2]\ is \"\$x \leq -2\".
