Suppose the graph of f is given. Describe how the graphs of the following functions can be obtained from the graph of f.

y=3f(-x)

To obtain the graph of y=3f(-x) from the graph of f, you would first reflect the graph of f across the y-axis to get the graph of f(-x). Then, you would stretch the graph vertically by a factor of 3 to get the graph of 3f(-x).
