For cubic equations in two variables, see cubic plane curve. Graph of a cubic function with 3 real roots (where the curve crosses the horizontal axisâwhere y = 0) (and hence no complex roots).n other words, a cubic function is defined by a polynomial of degree three. Setting Æ (x) = 0 produces a cubic equation of the form: Usually, the coefficients a, b, c, d are real numbers. However much of the theory of cubic equations for real coefficients applies to other types of coefficients (such as complex ones).
Neurosis (Boeree, 2006) is Karen Horneyâs theory about the ways in which people attempt to make life bearable for themselves. Unlike other theorists, Horney saw it as âcontinuousâ with normal life.
Finally, Ogden and Richards developed the Symbol Theory in order to explain how words expressed in communication evoke images, thus providing a personal meaning based on experience.ather than focus on a single idea upon which to base the theory, they deconstruct the idea into many parts, thus creating a multi-faceted theory to explain communication behaviors. The facets explored by Ogden and Richards include Meaning Theory, Definition Theory, and Symbol Theory.
