In Chapter 0 we learned about transforming parent functions. The original equation was y=|x|. The vertical translation of y=|x|+2 is moved up by 2. The horizontal translation of y=|x-2| is moved to the right by 2. The reflection of y=-|x| is reflected across the x axis. The combination of Vertical land Horizontal of y=|x+3|+1 is moved up by 1 and to the left by 3. The vertical stretch of y=|2x| is stretched by 2.
