Chapter 1.1, Problem 19E

To determine

**To sketch:** A rough graph of the height of the grass as a function of time over the period of four weeks.

Expert Solution

Let the time over four hour-week period (four Wednesdays) represented in the *x*-axis and the height of the grass over the week represented in the *y*-axis.

Generally, as days increases the length of the grass increases. Thus, the graph of the height of the grass as a function of time over the course of a four hour-week period is shown below in Figure 1.

In Figure 1, the open dot indicates that the point is excluded and the closed dot indicates that the point is included.

**Note:** The height of the grass for every week is not necessary to be same in length. So, the graph may vary depends on the grass height.
