Range

Describe the Range.

$frac1$

Step 1. Determine the equation of the horizontal asymptote.

Since the degree of the numerator is smaller than the degree of the denominator, the equation of the asymptote is y = 0.

Step 2. The range will be all real numbers excluding the value from step 1.

The range is: all real numbers excluding y = 0.

This can be written in set notation as: .
