Question

the mapping diagram shows a relation. what is the domain of the relation? × {x|x = -4, 0, 1, 2} ○ {x|x = -7, -6, 2, 3, 11} ○ {y|y = -4, 0, 1, 2} ○ {y|y = -7, -6, 2, 3, 11}

Explanation:

Step1: Identify domain definition

The domain of a relation is the set of all input values (the left oval in the mapping diagram).

Step2: List input values

The input values are $-6, 2, -7, 11, 3$.

Step3: Match to correct option

Sort and format the set to match the option style: $\{x|x=-7, -6, 2, 3, 11\}$.

Answer:

$\{x|x=-7, -6, 2, 3, 11\}$
