1. The problem statement, all variables and given/known data -5.978(1+5.71e^-.054x)/1+5.71e^-.054x logistical regression values from ti 83 a=5.71 b=.054 c=5.978 2. Relevant equations general logistical regresion model g(x) c/1+ae^-bx 3. The attempt at a solution So far I have applied the quotient rule to find the derivative of the general logistical model and come out to (1+ae^-bx)-c(1+ae^-bx)/(1+ae^-bx)^2 I took derivate and factored a little and came to this -c(1+ae^-bx)/1+ae^-bx At this point I just factored in the logistical information from my ti 83 which is a=5.71 b=.054 c= 5.978 I really need help factoring the numerator of this problem, and from there finding the 2nd derivative. I know at some point I must take natural log to both side of the equation to find the point of inflection. Please help me with this!
