Question 134755
The instructions say to graph each polynomial function. Factor first if the expression is not in factored form. 
f(x)=x^2(x-5)(x+3)(x-1) 
I'm not sure what to do with the x^2 
--------------------------------------
Since x^2 is one of the factors,x=0 is a zero (root) of multiplicity 2.
------------------------------
You also have zeroes at x = -3, x=1, and x=5
------------------------------------------
The y-intercept is 
y = 0*-5*3*-1 = 0
-----------------------
{{{graph(400,300,-10,10,-350,100,x^2(x-5)(x+3)(x-1))}}}
========================
