I need someone to help me (in very simple terms ;)) how to: Graph each polynomial function. Factor first if the expression is not in factored form.. f(x)=x^2(x+1)(x-1)

to graph polynomial function , firstly i will find the point which intersect x-axis. the point that intersect x-axis has y=0 to find that, 0=x^2 (x+1)(x-1) the values of x which fulfill the equation are x=0, x=-1, x=1 secondy, find the extreme point. use the derivative of the function \[f \prime x =4x ^{3}-2x ^{}=0\] so x=-1/2 and 1/2 then plug those value of x to the function to get the extreme value of y you'll get y = 1/16 so you'll have some points : (0,0) , (-1,0) , (1,0) (-1/2, 1/16), (1/2, 1/16) finally just connect that points so now you have the graph

sorry, the value of y extreme is not 1/16 . it's -1/16

so the extreme points is (-1/2, -1/16) and (1/2, -1/16)
