Use the display below to create this diagram. Right-click on the y-output box and select Show table.Then use the option given to add a graph. You should see the graph of y = 3x²+2. Change the display to produce the graphs of some of these: y = 2x²-3, y = 5x²+7, y = 4(x²-1), y = 3-5x², y = 2(1-4x²), y = -2x²+1, y = -3x²-2 Try these too: y = 2x³+1, 3(x³-4), y = 4/x, y = 5 - 2/x, y = 2x
