In Exercises 27 and 28, find the domain of the function represented by the graph. Determine whether the
domain is discrete or continuous. Explain.

                                             Question 27

The graph on question 27 indicates that there are three points with the locations such as:

In other words, there are three points that lie on the graph with the x-values such as:

{(2, 6), (4, 12), (6, 18)}

We know that the domain includes the set of x-values.

Hence, the domain of the function is:

Since the points are not connected between them. In other words, there is not a continuous line.

Thus, the function represented on the graph has a discrete domain.

                                        Question 28

The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).

Since there is a continuous line between the points from x = 0 to x = 7.

Thus, the domain of the line function is:

As the line segment is a continuous line. Thus, the domain is continuous.

answer: it would most likely be y=6 and 5/7.
