3.4: Graphs of Polynomial Functions - Mathematics LibreTexts 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. WebMathematically, we write: as x\rightarrow +\infty x +, f (x)\rightarrow +\infty f (x) +. If a polynomial of lowest degree phas zeros at [latex]x={x}_{1},{x}_{2},\dots ,{x}_{n}[/latex],then the polynomial can be written in the factored form: [latex]f\left(x\right)=a{\left(x-{x}_{1}\right)}^{{p}_{1}}{\left(x-{x}_{2}\right)}^{{p}_{2}}\cdots {\left(x-{x}_{n}\right)}^{{p}_{n}}[/latex]where the powers [latex]{p}_{i}[/latex]on each factor can be determined by the behavior of the graph at the corresponding intercept, and the stretch factor acan be determined given a value of the function other than the x-intercept. The multiplicity of a zero is important because it tells us how the graph of the polynomial will behave around the zero. Then take an online Precalculus course at So I'm liking choices B and D so far.
