Given the function f(x) sketched below, Homework Help ✎
Start by making a table of values for the given function.
Give each of the x-values in your table the opposite sign and graph the new function.
Since f(x) = y, give each of the y-values in your original table the opposite sign. Then graph the new function.
Add a third column to your original table labeled f(f(x)). Then, for example, f(f(–3)) = f(1) = –1.
