f(x)=9x^3 - 6x^2 + 5

Identifyany inflection points for f(x) and their type(stationary or non-stationary)

a Non stationary inflection point at x =2/9 since f'(x) <0 and f "(x) =0

b Non stationary inflection point at x =2/9 since f'(x) <0 and f "(x)>0

c Stationary inflection point at x =4/9 since f'(x) =0 and f "(x) =0

d Stationary inflection point at x =4/9 since f'(x) =0 and f "(x) >0

e Stationary inflection point at x =4/9 since f'(x) =0 and f "(x) <0

f Non stationary inflection point at x =2/9 since f'(x) >0 and f "(x) =0
