As in previous lessons, the process of using an equation of the form y = af(bx) to graph a function can be reversed to determine the equation of a function given a graph.
Try This 3
Janila is working on her transformation project and has drawn an original function, y = f(x), and transformed the function to produce y = g(x) and y = h(x). Determine an equation to represent g(x) and h(x) in terms of f(x).

“Example 4” on page 25 of the textbook shows an example of how the equation of a function can be determined from a graph. If you felt comfortable completing Try This 3, move on to Self-Check 4. If you want to see another example, read “Example 4.”
