Question

question 9 of 10, step 1 of 1
determine the domain and range for the relation.
r = {(x,y)|x ∈ n and y ∈ z}
domain
or
on
oz
range
or
on
oz
even r
even n
even z

Explanation:

Step1: Identify domain set

The domain is the set of all $x$-values in the relation. Here, $x \in \mathbb{N}$, so the domain is the set of natural numbers.

Step2: Identify range set

The range is the set of all $y$-values in the relation. Here, $y \in \mathbb{Z}$, so the range is the set of integers.

Answer:

Domain: $\mathbb{N}$
Range: $\mathbb{Z}$
