The graph of any cubic function is similar to such a curve. The graph of a cubic function is a cubic curve, though many cubic curves are not graphs of functions. Although cubic functions depend on four parameters, their graph can have only very few shapes. In fact, the graph of a cubic function is always similar to the graph of a function of ...
The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a , b , c , and d of the cubic equation are real numbers , then it has at least one real root (this is true for all odd-degree polynomial functions ).
Algebraic functions are functions that can be expressed as the solution of a polynomial equation with integer coefficients. Polynomials: Can be generated solely by addition, multiplication, and raising to the power of a positive integer. Constant function: polynomial of degree zero, graph is a horizontal straight line
According to Brooks' theorem every connected cubic graph other than the complete graph K 4 has a vertex coloring with at most three colors. Therefore, every connected cubic graph other than K 4 has an independent set of at least n/3 vertices, where n is the number of vertices in the graph: for instance, the largest color class in a 3-coloring has at least this many vertices.
Given a function: from a set X (the domain) to a set Y (the codomain), the graph of the function is the set [4] = {(, ()):}, which is a subset of the Cartesian product.In the definition of a function in terms of set theory, it is common to identify a function with its graph, although, formally, a function is formed by the triple consisting of its domain, its codomain and its graph.
For example, in the quaternions, a real number has infinitely many cube roots. Plot of y = 3 √ x. The plot is symmetric with respect to origin, as it is an odd function. At x = 0 this graph has a vertical tangent. A unit cube (side = 1) and a cube with twice the volume (side = 3 √ 2 = 1.2599... OEIS: A002580).
every cubic bridgeless graph without Petersen minor has a cycle double cover. [13] is the smallest cubic graph with Colin de Verdière graph invariant μ = 5. [14] is the smallest graph of cop number 3. [15] has radius 2 and diameter 2. It is the largest cubic graph with diameter 2. [b] has 2000 spanning trees, the most of any 10-vertex cubic ...
The Darboux cubic is the locus of a point X such that X* is on the line LX, where L is the de Longchamps point. Also, this cubic is the locus of X such that the pedal triangle of X is the cevian triangle of some point (which lies on the Lucas cubic).
