Definition: DomainThe domain of a function is the set of all x-values.

Since the x-values run from left to right in the coordinate plane, we read the values from left to right.

The domain of this function is [-6, 6]

Definition: RangeThe range of a function is the set of all y-values.

Since the y-values run up and down in the coordinate plane, we read from bottom to top

The range of this function is [-4, 8]
