Question: Graph the 4th degree polynomial with realcoefficients whose zeros are x=-2 (a repeated root), x=3 and x=0. Following all the graphing requirements as shown below:

- show the correct shape of the function without distortion or wasted space.

-show all the maxima, minima, and intercepts

-allow to read (x,y) coordinates of all the x and y intercepts and all the maxima and minima on the graph easily and clearly.

-have a...
