Which statement is correct for the interval (0, 4]?
Answer and explanation
Correct answer: 0 is not included and 4 is included.
In interval notation, a parenthesis means that the endpoint is excluded, while a square bracket means that the endpoint is included. The interval (0, 4] therefore excludes 0 because of the left parenthesis and includes 4 because of the right square bracket. It contains all real numbers greater than 0 and less than or equal to 4.
