Quadratic Function

​Domain- set of all first elements of the ordered pairs.

​ - known as abscissa (x)

Range - set of all second elements of the ordered pairs.

​ - known as ordinate (y)

​A function is a correspondence between the elements of the domain and the elements of the range such that each element of the domain corresponds to exactly one element in the range.

​The bridge resembles a common graph with a smooth U-shape called a parabola.

• ​the turning point of the graph

• ​an ordered pair with coordinates (h,k) where                        and

• ​called a minimum point if the graphs opens upward or ​maximum point if the graph opens downward.

​minimum point (0,0)

​maximum point (0,0)

​if a <0 the parabola opens downward = the vertex is the highest point
