1. Characteristics of Quadratic Functions

2. Vocabulary Domain: The set of all x-values (left to right)
Range: The set of all y-values (bottom to top)
Interval of Increase: The set of x-values where a function is going up.
Interval of Decrease: The set of x-values where a function is going down
Rate of Change: The slope of the line connecting two points (rise/run or (y2-y1)/(x2-x1))
End Behavior: The y value a function approaches as x gets extremely small ( - ) and extremely large ( )
