### Requirements

This activity helps students understand dilations of functions, where a dilation is a vertical or horizontal stretch or compression. When a function is multiplied by a number, the shape of the graph will retain its basic shape, though stretch or compress in different directions. By the end of the activity students will be able to identify a given function dilation, identify the way the graph will change and sketch a graph of the dilated function. This is the second of five activities about transformations of functions, focusing on: translations, dilations, reflections, all transformations, and inverses of functions.

## COMMON CORE STATE STANDARDS FOR MATHEMATICS (2010)

CCSS.Math.Content.HSF-BF.B.3 Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
