2.6: Families of Functions Flashcards
Parent Function
the simplest function with these characteristics. the equations of the functions resemble each other. so do the graphs.
translation
shifts a graph horizontally, vertically, or both.
stretch
multiplies all y-values by the same factor greater than 1, thereby stretching a graph vertically
shrink
reduces all y-values by a factor between 0 and 1, thereby compressing the graph vertically
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 _______, or change of a parent function
parameter
transformations take the same form using _____, like h, k, and a.
