An absolute value function is a function that contains an algebraic expression within absolute value symbols. Recall that the absolute value of a number is its distance from 0 on the number line. To graph an absolute value function, choose several values of x and find some ordered pairs. Also, if a is negative, then the graph opens downward, instead of upwards as usual.

Quadratic Functions in Vertex Form. Author: Terry Gastauer. Topic: Functions , Quadratic Functions. The graph of a quadratic function produces a parabola. Every parabola has either a maximum or minimum value located at its vertex.
The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape. The picture below shows three graphs, and they are all parabolas. All parabolas are symmetric with respect to a line called the axis of symmetry. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.
