Question

a bus can transport a certain number of students. use the graph of the step function to find the number of buses that are needed to bring 65 students to school.

Explanation:

Step1: Analyze the intervals

The step - function graph has intervals:

• \(0\lt x\leqslant32\), \(y = 1\)
• \(32\lt x\leqslant64\), \(y = 2\)
• \(64\lt x\leqslant96\), \(y = 3\)
• \(96\lt x\leqslant128\), \(y = 4\)

Step2: Locate \(x = 65\) in the interval

Since \(64\lt65\leqslant96\)

Answer:

\(3\)
