2. `y=(x^2+2x-3)/(x^2-5x-6)`, find Asymptotes of a function

Solution:
Asymptotes :
Now, find domain of `y=(x^2+2x-3)/(x^2-5x-6)`

`y=(x^2+2x-3)/(x^2-5x-6)`

`x^2-5x-6=0`

`=>x^2-5x-6=0`

`=>x^2+x-6x-6 = 0`

`=>x(x+1)-6(x+1) = 0`

`=>(x+1)(x-6) = 0`

`=>(x+1) = 0" or "(x-6) = 0`

`=>x = -1" or "x = 6`

Domain : `x!=-1,x!=6`

Vertical asymptote : `x=-1,x=6`

The highest power in the numerator is 2
The highest power in the denominator is 2
Horizontal asymptote : `y=1`

Slant(Oblique) asymptote : none
