SOLUTION: f of(x)=x(to the third)-5x(squared)-25x+125, find the zeros. For each zero you find, state whether the graph of f(s)crosses or only touches the x-axis.

---------------
f(x)=x^3-5x^2-25x+125
By graphing I find:
x=-5 is a zero that cosses the x-axis
x=5 is a zero that only touches the x-axis.
