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.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
