Question

4.) Consider the following relation represented as a set of ordered pairs.(4,8), (5, 2), (3,7), (4, 2), (2,7), (1, 10), (5, 8)a.) Represent the relation as a table. b.) Graph the relation. c.) Is this relation a function? Explain in the space below.

Answer 1

We have

the point is (x, y)

a)

then the table is

x y

4 8

5 2

3 7

4 2

2 7

1 10

5 8

b)

c)

that's not a function because we can't repeat the same value in x, in other words, we can't have two values of y in the same x value

and we repeat in

(4,8) (4,2)

(5,2) (5,8)
