Question

look at this set of ordered pairs: (13, 6) (5, 15) (5, -17) (-8, 4) (-11, 19) is this relation a function? yes no

Explanation:

Step1: Identify input values

Input values (x-values): $13, 5, 5, -8, -11$

Step2: Check for repeated inputs

The input $5$ maps to two outputs: $15$ and $-17$.

Step3: Apply function definition

A function requires each input to have exactly one output. Since $5$ has two outputs, the relation is not a function.

Answer:

no
