The four functions below all have vertical asymptote(s) and have either a slant asymptote or a horizontal asymptote. For each of the functions, state a) the equation of all vertical asymptotes, and b) state whether the function has a slant asymptote or horizontal asymptote and it's equation.
1. f(x)=(x-5)(x+6)(x-2)/(x+1)(x-3)
2. f(x)=3x/(x+5)
3. f(x)=2(x-5)(x+3)/(x-2)
4. f(x)=(x+1)/2(x-4)(x+3)
