How Do Graphs Differ?
Suppose that the graph of a function f is known. Explain how the graph of y = 4•f(x) differs from the graph of y = f(4x).
Let me see.
For the graph of y = 4•f(x), we stretch the graph vertically because 4 > 1.
For the graph of y = f(4x), we compress the graph horizontally because 4 > 1.
You say?

It's good to know that I can think my to the right answer by reading the problem several times.
