Question

in the relation {(1, 4), (-2, 2), (2, 2), 1, -4)}, which of the following numbers is part of the domain?

Answer 1

Answer:

{- 2, 1, 1, 2}

Step-by-step explanation:

Firs of all the relation is not a function, because two points (1, 4) and (1, - 4).

Domain is set of all first elements of ordered pairs (x-values, or inputs)

Domain: {- 2, 1, 1, 2}

FYI,

Range: {- 4, 2, 2, 4}
