1. Without graphing: a. describe the transformation from the graph of f(x) = x2 to the graph of
g(x) = x2 + 7
b. Suppose f(x) = x - 2. Describe the transformation from the graph of f(x) to the graph
of
g(x) = x + 3. Use a graphing calculator to check your answer.
Ray's Gym charges an initial sign-up fee of $25.00 and a monthly fee of $15.00.
2. a. Write a function that describes the gym's total membership fee for x months.
b. Graph the function you wrote in Item 3 with several points on the graph.
c. Identify the y-intercept. What does the y-intercept represent?
3. How would the function change if the initial sign-up fee were increased by $5.00? How
would the graph change?
4. The membership fee at Gina's Gym is given by the function g(x) = 15x + 20, where x is the
number of months.
a. How do the fees at Gina's Gym compare to those at Ray's Gym?
b. Without graphing, describe how the graph of g(x) compares to the graph of f(x).
5. The y-intercept of a function f(x) is (0, b). What is the y-intercept of f(x) + k?
