Question

look at this set of ordered pairs: (0, -16) (-16, 2) (18, 19) (17, 4) (12, 9) is this relation a function? yes no

Explanation:

Step1: Identify input (x) values

Input values: $0, -16, 18, 17, 12$

Step2: Check for repeated x-values

All x-values are unique; no duplicates.

Step3: Apply function definition

A relation is a function if each input has exactly one output. Since no x-value repeats, each input maps to one output.

Answer:

yes
