Graphing Calculator Group Activity Using graphing calculators, graph the following 2 sets of functions. Within a group of 4, each 2 students work on 1 set. Compare and contrast the graphs, What can you conclude?

Terms to Know Vertical Dilation: is s type of transformation that stretches or compresses an entire figure or graph. Vertical Stretching: is the stretching of the graph away from the x-axis. Vertical Compression: is the squeezing of the graph towards the x-axis. Reflection: is a mirror image of a graph across its line of reflection. Line of Reflection: is the line that a graph is reflected across.
