need to make the graphic look of the next function ....

f (x) = 3x ^ 5 - 5x ^ 3

necesiton tell me what are the critical points of max / min and inflection

k ii is not know how to get them if the teacher told us that the critical points of max / min are:
x = 0
x = 1
x =- 1

ii the inflection:
x = 0
x = sqrt (1 / 2)
x = sqrt (-1 / 2)

my question is komo aki get x = 0 and x = sqrt (-1 / 2), because the other critical points if I could get ... I hope and help me ....

graciiaas ... in advance ....
