Module 1: Function Transformations
In Try This 3 you may have found that when y = f(x) is reflected across the y-axis, the graph of y = f(−x) is produced. Also, when y = f(x) is reflected across the x-axis, the graph of y = −f(x) is produced.
Read “Example 1” and its solution on pages 18 to 20 of the textbook to view a comparison of the graphs y = f(x), y = −f(x), and y = f(−x).
