What would be the equation of this transformed graph? exercise: Write the equation of a parabola with vertex (0,−23). Unit 1 – Day 4: Graphing y = x + q and y = (x−p) 2 2 Page 3 of 4 GRAPHING y = (x − p)2 example: For the function y = (x − 6)2 : • Complete the table of values. x p= ● Use the table to draw the graph of this function. y x − 6...
