Question

look at this set of ordered pairs: (20, 13) (-8, 14) (20, 18) (0, 10) (-8, 10) (0, 14) is this relation a function? yes no

Explanation:

Step1: Recall function definition

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

Step2: Check x - values

• For \(x = 20\), we have \(y = 13\) and \(y = 18\).
• For \(x=- 8\), we have \(y = 14\) and \(y = 10\).
• For \(x = 0\), we have \(y = 10\) and \(y = 14\).

Since there are x - values with more than one y - value, the relation is not a function.

Answer:

no
