no ideas on any of those answers?

vertical asymptotes where denominator is zero

horizontal asymptote is y=0, since denominator has higher power

increasing where y' > 0

max/min where y' = 0 and y'' not zero

concave up where y'' > 0

inflection where y'' = 0

y' = 4x/(x^2-9)^2

y'' = 12(x^2 + 3)/(x^2 - 9)^3
