Power function calculator with points can help students to understand the material and improve their grades. A polynomial function of \(n^\text{th}\) degree is the product of \(n\) factors, so it will have at most \(n\) roots or zeros, or \(x\)-intercepts. Steps for that are as follows:. Describe the end behavior, and determine a possible degree of the polynomial function in Figure \(\PageIndex{9}\). You can find a base-10 log using most scientific calculators. Each product \(a_ix^i\) is a term of a polynomial function. The \(x\)-intercepts are \((0,0)\),\((3,0)\), and \((4,0)\). Mathematics is the study of numbers, shapes, and patterns. Given the function \(f(x)=3x^2(x1)(x+4)\), express the function as a polynomial in general form, and determine the leading term, degree, and end behavior of the function. These examples illustrate that functions of the form \(f(x)=x^n\) reveal symmetry of one kind or another. This polynomial is considered to have two roots, both equal to 3.
