Investigation of f(ax)
Our last function transformation is f(ax). This is multiplying x by a everywhere it appears in the function.
As usual, our linear function might lead us astray here. Make sure you check all functions and observe carefully.
Also, check carefully, some things might work the opposite way than you might expect!!
Answer these questions:
When a increases what effect does this have on the function?
When a decreases what effect does this have?
When a is negative what effect does this have?
