Polynomial GraphsA series of free Intermediate Algebra Lessons from Brightstorm online Algebra series.
Basic Polynomial Graphs Graphing higher degree polynomial functions can be more complicated than graphing linear and quadratic functions. Polynomial graphs can be graphs of functions where the degree of the highest term is greater than one. When we graph polynomials with varying degrees it is easier to identify the end behavior, shape and turning points.
Basic Transformations When graphing polynomials, basic transformations occur when a graph either shifts along the x-axis or y-axis and/or dilates. When graphing transformations, a dilation occurs when the "a" term value is changed. Dilations cause the parabola to either open a different direction or change shape. A shift occurs when a graph doesn't change shape but moves along the x or y axis.
