Find the domain and range of the relation show on the graph

Answer 1

How to identify domain and range from coordinate pairs?

• If x,y is a pair then x is domain and y is range.

Here

• Domain is [0,4]

Here range is

• (-oo,oo)

Answer 2

The domain of the relation is 0 ≤ x ≤ 4

The range of the relation is all real numbers (-∞, ∞)

Explanation:

Domain : the set of possible x-values (the "input" values)

Range : the set of y-values (the "output" values)

The domain of the relation is 0 ≤ x ≤ 4

The range of the relation is all real numbers (-∞, ∞)
