1. Section 3-2: Analyzing Families of Graphs A family of graphs is a group of graphs that displays one or more similar characteristics. A parent graph is a basic graph that can be transformed to create the other members in the family.

2. Section 3-2: Analyzing Families of Graphs A line reflection flips a graph over a line called the axis of symmetry. The shifting of a graph either vertically or horizontally is called a translation. A dilation is a stretching or compressing of a graph.
