2.6 Families of Functions Flashcards
Parent Function
is the simplest function with these characteristics. The equations of the functions in a family resemble each other.
Translation
shifts a graph horizontally, vertically, or both, it results in a graph of the same shape and size but possibly in a different position.
Stretch
a vertical stretch multiplies all y- values by the same factor greater than 1.
Shrink
a vertical shrink reduces y-values by a factor between 0 and 1, there by compressing the graph vertically.
Reflection
a reflection in the x-axis changes y-values to their opposites, ,when you change the y-values of a graph to their opposites, the graph reflects across the x-axis.
Transformation
each member of a family of functions is a transformation, or change, of a parent function.
Parameters
algebraically the transformations take the same from using parameters, like h,k, and a.
