#### Answer:

Domain =

Range =

#### Explanation:

This will be undefined where the denominator is 0:

So the domain will consist of all points where x doesn't equal

Domain =

Since the denominator has a higher degree than the numerator, the rational equation has a horizontal asymptote at y = 0.

This means the range will consist of all points where y doesn't equal 0

Range =
