3	0.3
5	2.3
7	4.3
9	6.3

a. the table is a function since none of the y’s repeat
b. the table is a function since none of the x’s repeat
c. the table is not a function since none of the y’s repeat
d. the table is not a function since none of the y’s repeat

1. does the following relationship represent a function?

Explanation:

8.

Step1: Recall function definition

A relation is a function if for each input (x - value) there is exactly one output (y - value).

Step2: Check x - values in table

In the given table, the x - values are 3, 5, 7, 9. None of the x - values repeat.

Step1: Recall function definition

A relation is a function if for each input (x - value) there is exactly one output (y - value).

Step2: Check x - values in relation

In the relation \(\{(2,0),(2,3),(4,5),(9,0)\}\), the x - value 2 has two different y - values (0 and 3).

Answer:

B. the table is a function since none of the x’s repeat
