a.

b.

c.

d.

The domain is the set of all *x*-values of a relation or function.

The range is the set of all *y*-values of a relation or function.

For a relation to be a function, each *x*-value must correspond to only one *y*-value.

Domain: −3 ≤ *x* ≤ 3

Range: −3 ≤ *y* ≤ 3

Not a Function

Domain: −3 ≤ *x* ≤ 4
