-2 three times

-1 nine times

4 two times

My question is how the graph would look like. I guessed that since there really is only 4 x-intercepts and that the rest just overlap, that it's a quartic function, therefore giving the shape M.

But then it's a 16 degree polynomial so it doesnt make sense, is it a combination of quartics and cubics? Can someone help?
