1-21.

Given the functions below, compute the following values

Calculate ,, and.can be called, informally, the Boundary Point of the piecewise function. This is becauseis the location where the left and the right pieces switch.andare on the left side of the Boundary Point,is on the right side of the Boundary Point.LEFT PIECELEFT PIECERIGHT PIECECalculate ,, and.The Boundary Point is

. So lies on the left side of the piecewise function whileandlie on the right.Calculate ,,, and.This function has two boundary points and three pieces: a left piece, a middle piece and a right piece.
