Chapter 3: The nature of Graphs Section 3-2: Families of Graphs Parent Graphs-”Mom and Dad” A parent graph is the basic graph that is transformed to create other members (children) in a family of graphs. A mom absolute value function y = x and a dad absolute value function y = - x will produce ONLY absolute value children. The children are all transformations of either mom or dad. Example y = x + 3 − 4 . All of the graphs of absolute value functions have similar characteristics. They are all V shaped. Families of Graphs Reflections and translations A transformed graph may appear in a different location on the graph, but it will resemble the parent graph. It is much easier to do transformations of a function if the parent graph is known. Relationships in families of graphs Dilations A dilation of a graph means that you expand it or compress it.
