Question 804410
{{{f(x)=( x^2+2x-3)/(x^2+4x+3)}}}
For finding the horizontal, you want to look for the x with the highest degree for the numerator and denominator. Get rid of everything else
For this equation {{{x^2/x^2}}} is what we are looking at.
You find the horizontal, you need to start by plugging in numbers
You can plug in any number you want.
{{{1^2/1^2=1}}}
{{{20^2/20^2=1}}}
{{{23456^2/23456^2=1}}}
No matter what number you plug in, you will always get 1 so y=1 is your horizontal asymptote
