10 Practice 1. Predict how each function will change from the parent function y = x2. Write a short sentence describing the transformation. Example: y = 2x+ 6 The graph will be translated up by 6 units. It will also stretch vertically by a factor of 2. a) y = x2 - 2 b ) y = 2x2 c) y = 0.5x2 d) y = 0.5x2 + 8 e) y= 4x2 - 1 f) y = 0.2x2 + 4 g) y =-3x2 - 9 2. If you were to try graphing quadratics with different values of h and k, would it be easy to predict the location or shape of the graph base on the value of h and k? Explain
