Give two other examples of step functions that arise in everyday life.
Function involving this sort of “milestone” system will be graphed as a step function.
The functions in Example 10 and Exercise 61(a)are called step functions because their graphs look like stairs. Give two other examples of step functions that arise in everyday life.
Consider the graph of the number of runners who have crossed the finish line in a race vs. time.
In this graph, shown here in the range 10

From the graph we see that there are six distinct salary levels, all increasing as an employee hits a certain number of years spent at the firm.
Hence, any function involving this sort of “milestone” system will be graphed as a step function.
