On the dependence polynomial of a graph - Qian, Dress, et al. () Citation Context ...umber of independent points of G, then its independence polynomial is the polynomial IG(x) := α∑ r=0 ir(G) · xr = ∑ I x|I|, (1.3) where the sum is over all independent subsets I ⊆...
Let G be a connected graph on n vertices with adjacency matrix AG. Associated to G is a polynomial dG(x1,…,xn) of degree n in n variables, obtained as the determinant of the matrix MG(x1,…,xn), where MG=Diag(x1,…,xn)−AG. We investigate in this article the set VdG(r) of...
Sketch a graph of f(x)=14x(x−1)4(x+3)3.f(x)=14x(x−1)4(x+3)3. Show Solution Writing Formulas for Polynomial Functions 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...
The exponent says that this is a degree-4 polynomial; 4 is even, so the graph will behave roughly like a quadratic; namely, its graph will either be up on both ends or else be down on both ends. Since the sign on the leading coefficient is negative, the graph will be down on both...
In some situations, we may know two points on a graph but not the zeros. If those two points are on opposite sides of the x-axis, we can confirm that there is a zero between them. Consider a polynomial function f whose graph is smooth and continuous. The Intermediate Value Theorem ...

Fig. 1.1b is a graph of the following polynomial equation: (1.13)x4+7x3+12x2−4x−16=0 which has two real and distinct roots at −4 and 1, and two real and repeated roots at −2. The point of tangency with the x-axis indicates the presence of the repeated roots. At this...
