In other words, the model equation can contain all sorts of expressions like roots, logarithms, etc., and still be linear on the condition that all those crazy stuff is applied to the independent variable(s) and not to the coefficients. When this happens, we may employ a computer that solves using numerical computation. Consider the same rectangle of the preceding problem. OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. With its help, you'll be able to quickly determine the polynomial that best fits your data. ) Higher degree polynomials can be factorized using the remainder theorem to create a quadratic function. are graphs of polynomial functions. The graph touches the axis at the intercept and changes direction. The Intermediate Value Theorem states that if Polynomial comes from poly- (means "many") and -nomial (means "term") so polynomial means "many terms". (x2) 3 Pre-Algebra.
