Consider the function [math]f(x) = x^2[/math], its graph, and the constant [math]k = 4[/math]. What is [math]f(x + k)[/math]? How are the graphs of [math]f(x)[/math] and [math]f(x + k)[/math] different?
[list=1] [*]Substitute the value of [math]k[/math] into the function. [*]Use a table of values to graph the two functions on the same coordinate plane. [*]Compare the graphs of the functions. [/list]
