Hi. This is more of a pre-calc question. I was asked to create a formula for a polynomial function with the following information: degree of 4, a zero at x=2, symmetric about the y-axis, vertical intercept at y=90, and a point at (-1, -60). From that, I gathered that since it is symmetric about the y-axis(even) that all powers must be even. Since it is a degree of 4, IF there is another zero, it can only be of the degree 4 or 2, and the zero I'm given can only be of the degree 4 or 2. Help!
