Chapter 7.5, Problem 60E

To determine

To Find: Whether the domain is discrete or continuous and graph the function as the domain.

Answer to Problem 60E

The domain is continuous and the graph is shown in Figure 1

Explanation of Solution

Given:

The cost of the broccoli per pound is $\$2$ .

The total cost $t$ of the broccoli is the function of the number of pound $p$ .

Calculation:

Consider the cost of the broccoli per pound is $\$2$ and the total cost $t$ of the broccoli is the function of the number of pound $p$ . Then, the function is,

  $t=2p$

Thus, the domain is continuous.

The graph for the above function is shown in Figure 1
