An interval as a set of numbers. Numbers = endpoints.
Inequality Sign Evaluation
You entered the ≤ sign
Build the interval notation for x:
Because you entered an equal sign Translate to ] since we include the number 5
Based on the ≤ you entered, the left side of the interval notation will extend to negative infinity, which is denoted as -∞
