GRAPHING QUADRATIC FUNCTIONS A quadratic function has the form Where a is not equal to 0. The graph of a quadratic function is U-shaped and is called a parabola.

The axis of symmetry is the vertical line x=-b/2a.

STANDARD FORM OF A POLYNOMIAL FUNCTION & END BEHAVIOR; The standard form of a polynomial function arranges the terms by degree in descending numerical order. The degree of a polynomial function affects the shape of its graph and determines the maximum number of turning points, or places where the graph changes direction. It also affects the end behavior, or the directions of the graph to the far left and to the far right. [See page 282 example]
