If the Polynomial is compatible for easy factoring, find the all possible zeros. To find polynomial equations from a graph, we first identify the x- intercepts so that we can determine the factors of the polynomial function. We can also identify the sign of the leading coefficient by observing the end behavior of the function. I will be going over how to use the leading term of your polynomial function to determine the end behavior of its graph. We will also be looking at finding the zeros, aka the x-intercepts, as well as the y-intercept of the graph.
