Q. What inequality represents this interval?(−∞,3]Choices:(A) x<3(B) x≥3(C) x≤3(D) x>3
Identify Endpoints: Identify the endpoints of the interval and whether they are included in the set. The interval is (−∞,3], which means that the endpoint 3 is included, but −∞ is never included because it is not a finite number.
Determine Inequality: Determine the inequality that corresponds to the interval. Since 3 is included, we use the "less than or equal to" symbol (≤) for the endpoint 3. The interval extends to negative infinity, which means all numbers less than or equal to 3 are included.
Match with Choices: Match the correct inequality with the given choices. The interval (−∞,3] corresponds to the inequality x≤3, which is choice (C).
