Part B: Compare the Graphs of f(x) = x2 and f(x) = x2 + q 4. a) Graph the following functions on the same set of coordinate axes, with or without technology. f ( x) = x2 f (x) = x2 + 4 f ( x) = x2 - 3 b) Describe how the graph of each function compares to the graph of f (x) = x2. c) What relationship do you observe between the parameter, q, and the location of the corresponding graph? 5. a) Using a variety of values of q, write several of your own functions of the form A(x) = x2 + q. Include both positive and negative values. b) Predict how these functions will compare to f(x) = x2. Test your prediction. Reflect and Respond 6. Develop a rule that describes how the value of q in f(x) = x2 + q changes the graph of f(x) = x2 when q is a) a positive number b) a negative number
