Write some code that will plot this polynomial $-x^3 - x^2 + 2 x$ between $x=-3$ and $x=2.$ Find the zeros of this polynomial from your graph. You can make a quick plot like this:px={} py={} k = 0 for x= ??,??,?? do px[k] = x py[k] = some function of x k = k + 1 end lineplot(px,py)This fills the arrays px and py with points, solineplotcan plot them.
