Take a look at teen 1's initial polynomials for three layers of hills. teen 1 has described what he thinks each modification to the initial polynomial will do. sketch each curve (in a different color, preferably). (you will be asked to find and repair mistakes in the next section.) (6 points: 2 points for each curve)

write equations for three hills that do meet the requirements. sketch them on one axis. (for the purposes of this exercise, this is a sketch, so the steepness and minimums and maximums of the graphs do not need to be exact).
