analaze the graph of y = 2/ (x^2-9)
y-intercepts: ____________________
vertical asymptotes: ____________________
horizontal asymptotes: ____________________
increasing intervals: ____________________
decreasing intervals: ____________________
relative maxima: ____________________
relative minima: ____________________
concave up intervals: ____________________
concave down intervals: ____________________
inflection points: ____________________
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
