Question:

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)

Answers

Answer:a) See attachment for graphb) Not a functionStep-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.
