I have noticed a few other people who post school questions on here so I figured why not see if anyone can help me try to understand Pre-Cal. If you can please answer one of these questions or more.
Find the slant assymtope of the rational function:
f(x)=2x^3-x^2-22x-28/(x^2-3x-4)
find the vertical assymtopes for
f(x)=(5x-3)(x^2+2x-3)
find the horizontal assymtopes of th rational function
f(x)=7x/(x^2-5)
Thank You!!

Divide numerator by denominato getting 2x+5 +R where r is the remainder and 2x +5 is the polynomial part. The slant asymptote is then y= 2x+5
x^2+2x-3= (x+3)(x-1)
Therefore vertical asymptotes occur at -3 and 1 since the denominator is 0 athese x values.
Horizontal asymptotes occur only when the degree of the numerator is the same as the degree of the denominator. Since the degree of the numerator is < degre of denominator, there are no horizontal asymptotes for this function
