Graph the given relation or equation and find the domain and range. then determine whether the relation or equation is a function.
(3.1, 5.1), (–1.9, 5.1), (–4.9, 3.1), (–4.9, –2.9)

a) See attachment for graph

b) Not a function

Step-by-step explanation:

The given set of ordered pairs are:

(3.1, 5.1), (–1.9, 5.1), (–4.9, 3.1), (–4.9, –2.9)

We plot the points and connect them with straight lines to obtain the graphs in the attachment.

We can see from the graph that a vertical line drawn at x=-4.9 cuts the graph at many points.

Since the graph of the relation fails the vertical line test, it is not a function.

You can also see from the ordered pairs that -4.9 has two different y-values 3.1 and -2.9.
