SP #2: Unit E Concept 7: Graphing a polynomial and identifying all key parts

Before looking down below for the extra help or wanting to know the answers please try to solve this problem by yourself:
x^4+x^3-16x^2+20x

In this problem you will be reviewing in how to solve a polynomial expression by finding the zeroes and the multiplicity's found and how to graph them without using a calculator. With the picture below you will be able to see the way to find the zeroes and multiplicities as well as graphing them out.

Please pay special attention in how to find the multiplicities and in how they will affect your graph. As well be sure to (if wanted) to plug back in the zeroes found to see if they are correct and to be sure that they make sense on the graph. Be sure to label out the graph as you put the points on there.
