Observe the table:

a.

Graph of the data with population on the horizontal axis and representatives on the vertical axis.

Since population is on the horizontal axis, these are the -values of the relation or the domain.

The number of representatives is the range.

Plot the data from the table as ordered pairs are

.

b.

Find the Domain and range values.

The members of the domain are the -values of the relation while the members of the range are

the -values.

Domain: .

Range: . 

c.

Find the relation discrete or continuous.

The domain is a set of individual points.

So the relation is discrete.

d.

Find the relation a function.

The relation is a function because each domain value is paired with only one range value.

So the relation is a function.

a. Graph:

The ordered pair is .

b. Domain is  and range: .

c. The relation is discrete.

d. The relation is a function.
