Q. What inequality represents this interval?(−∞,−2]Choices:(A) x<−2(B) x≤−2(C) x>−2(D) x≥−2
Identify Endpoints: Identify the endpoints of the interval and whether they are included in the set. The interval (−∞,−2] has −∞ as the lower bound and −2 as the upper bound. The square bracket at −2 indicates that −2 is included in the interval.
Determine Inequality: Determine the inequality that corresponds to the interval. Since −∞ 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 is included, the inequality must have an equal sign for −2.
Choose Symbol: Choose the correct inequality symbol. The interval extends from −∞ up to and including −2, which means the values that x can take are less than or equal to−2.
Match Inequality: Match the correct inequality with the given choices. The inequality that represents the interval -\infty, -2]\ is \"\$x \leq -2\".
