Question

Each graph shows a relation. The first and second numbers of each ordered pair in the relation are members of the set of real numbers. In each case, find the domain and the range of the relation and determine whether the relation is a function.

Answer 1

Answer:

The Domain is -2 [is less than or equal to] x < 0

The Range is 0 [is less than or equal to]  y < 2

This is NOT a function

Step-by-step explanation:

sry if this is a bit confusing:

[is less than or equal to] is just the sign that means what is said; this is bc you cant use that sign on keyboard

Answer 2

Answer:

• Domain: [-1, 0) U [2]
• Range: [0, 1)
• A function

Step-by-step explanation:

The domain is the set of x values and the range is the set of y values.

For the relation to the function, each value of x must map onto no more than one value of y.
