Each x-intercept corresponds to a zero of the polynomial function and each zero yields a factor, so we can now write the polynomial in factored form. Here, we will be discussing about Write an equation for the 4th degree polynomial graphed below. Specifically, we will find polynomials' zeros (i.e., x-intercepts) and With a constant term, things become a little more interesting, because the new function actually isn't a polynomial anymore. For polynomials without a constant term, dividing by x will make a new polynomial, with a degree of n-1, that is undefined at 0.
