If we sum up the information, we can conclude that the capacity of the theater is students. This means that the drama club should do performance for each group of students. Let's write a pattern if is the number of students and is the number of performances.
The function we wrote pairs every number in each interval with the single value. Therefore, it is a step function. Each piece of its graph will be horizontal line that is missing its left endpoint. We will show the left endpoints by open points and the right endpoints by a closed points. Let's graph it!
