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.
For f(x)= 1 divided by x^2-2x-8, find the interval(s) where f(x)<0. My answer is after plotting it out; (-2,4) could this be right. thanks for looking it over with me.
