Q. Which interval notation represents the set of all numbers greater than −8 and less than or equal to 12 ?(−8,12](−8,12)[−8,12][−8,12)
Identify Inequality: Identify the inequality that matches the description.Greater than −8 is written as x > -8.Less than or equal to 12 is written as x≤12.Combine them to get -8 < x \leq 12.
Combine Inequalities: Convert the inequality to interval notation.The symbol "(" represents numbers greater than but not including the endpoint.The symbol "]" represents numbers up to and including the endpoint.So, the interval notation is (−8,12].
