Consider the function [math]f(x) = x^2[/math], its graph, and the constant [math]k = 2[/math]. What is [math]k \bullet f(x)[/math]? How are the graphs of [math]f(x)[/math] and [math]k \bullet f(x)[/math] different? How are they the same?
[list=1] [*]Substitute the value of [math]k[/math] into the function. [*]Use a table of values to graph the functions. [*]Compare the graphs. [/list]
