Question

look at this set of ordered pairs: (9, 7) (-12, 9) (9, -14) (14, 1) 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: Identify duplicate x-values

Check x-values: 9, -12, 9, 14. The x-value 9 appears twice, paired with y=7 and y=-14.

Step3: Apply function rule

Since x=9 maps to two different y-values, the relation fails the function test.

Answer:

no
