Take Note: Summarize the process used in Problem 6 to rewrite the radical function y=\sqrt{9x+18} so that it can be graphed using transformations. You may use the canvas to help illustrate your written summary.

Problem 6 Got It? How can you rewrite the cube root function below so that you can graph it using transformations. Describe the graph.

Stretch the graph of the parent function vertically by a factor of 2, translate 4 units left, and translate 2 units down.

Stretch the graph of the parent function vertically by a factor of 2, translate 2 units left, and translate 4 units up.

Stretch the graph of the parent function vertically by a factor of 2, translate 4 units right, and translate 2 units down.

F.IF.7.b

Problem 6 Got It? Reasoning: Describe the graph of y = |9x - 18| by rewriting it in the form y = a|x - h|. How is this similar to rewriting the square root equation below (from Problem 6)?

|9x - 18| = 9|x - 2|; the graph of y = 9|x - 2| is the graph of y = |x| stretched vertically by a factor of 9 and translated left 2 units; in both cases, you are rewriting the function so that x has a coefficient of 1.

|9x - 18| = 9|x - 2|; the graph of y = 9|x - 2| is the graph of y = |x| stretched vertically by a factor of 2 and translated right 9 units; in both cases, you are rewriting the function so that x has a coefficient of 1.
