Question

determine whether the relation is a function.
$c=\\{(8,3), (-10,-3), (1,3), (5,-10)\\}$

is the relation a function?
no
yes

Explanation:

Step1: Identify input values (x-values)

The x-values are $8, -10, 1, 5$

Step2: Check for repeated x-values

Each x-value appears exactly once.

Step3: Apply function definition

A relation is a function if every input has exactly one output. Since no x-value repeats, this condition is satisfied.

Answer:

Yes
