Q. What inequality represents this interval?[−4,∞)Choices:(A) x>−4(B) x<−4(C) x≤−4(D) x≥−4
Identify Endpoints: Identify the endpoints of the interval and whether they are included in the interval. The interval is [−4,∞), which means −4 is included (as indicated by the square bracket) and ∞ is not included (as indicated by the parenthesis).
Determine Inequality: Determine the inequality that corresponds to the interval. Since −4 is included, the inequality must use either ≤ (less than or equal to) or ≥ (greater than or equal to). Since the interval extends to positive infinity, the inequality must allow for all numbers greater than or equal to −4.
Match Correct Inequality: Match the correct inequality with the given choices. The interval [-4, \infty)\] corresponds to the inequality \$x \geq -4, which means that x is greater than or equal to −4.
