You can make an absolute value function by dragging the RED points almost anywhere on the screen (why almost?). [br]The function will have the form[br][br] [math]m|x-X_0|+Y_0[/math][br][br]Now try to build the same absolute value function putting in values for m, [math]X_0[/math] and [math]Y_0[/math].[br] [br]Try to do this without displaying the functional form of the RED absolute value function you have made.[br][br]You can check your work by showing the expressions for the functions on the screen.
