1. The problem statement, all variables and given/known data let f(x)=(x+1)^2(x-2) a)Find the max and Min values of f(x) b)Find the inflection point of concavity 2. Relevant equations using defferentiation 3. The attempt at a solution for part a) differentiate (x+1)^2(x-2) we get ans=3(x-1)(x+1) Plse check for me? than f'(x)=0 therefore the points i got is x=1 and x=-1 respective?? the second part not sure..plse assist.
