Question

1. find the horizontal asymptote for $y = \frac{x^2 + 2x - 3}{x - 3}$

options:
$y = 3$
$y = 0$
none
$y = 1$

Explanation:

Step1: Check degrees of numerator and denominator

Degree of numerator $x^2+2x-3$ is 2, degree of denominator $x-3$ is 1.

Step2: Determine horizontal asymptote

When degree of numerator > degree of denominator, there is no horizontal asymptote.

Answer:

none
