Graphing a step function

i need

Shown below

A step function is a function defined by two or more functions. To graph this function, we can follow these steps:

STEP 1. Plot two endpoints for the line segment representing over the domain . These two endpoints are . At we draw a hole because the symbol < doesn't include this value and at we draw a dot because the symbol ≤ includes this value.

STEP 2. Plot two endpoints for the line segment representing over the domain . These two endpoints are . At we draw a hole because the symbol < doesn't include this value and at we draw a dot because the symbol ≤ includes this value.

STEP 3. Plot two endpoints for the line segment representing over the domain . These two endpoints are . At we draw a hole because the symbol < doesn't include this value and at we draw a dot because the symbol ≤ includes this value.

The resulting graph is shown below.

2,600 divided by 80 = 32.5

step-by-step explanation:

the first dot plot best represents the data
