Now that we know how to find zeros of polynomial functions, we can use them to write formulas based on graphs. Because a polynomial function written in factored form will have an x-intercept where each factor is equal to zero, we can form a function that will pass through a set of x-intercepts by introducing a corresponding set of factors. Add comment. Find the size of squares that should be cut out to maximize the volume enclosed by the box. Table 1. Graphs of polynomials either "rise to the right" or they "fall to the right", and they either "rise to the left" or they "fall to the left." At x= 3 and x= 5,the graph passes through the axis linearly, suggesting the corresponding factors of the polynomial will be linear. A "passing grade" is a grade that is good enough to get a student through a class or semester.
