CH1 Graphing Functions

The graphing function I used is f(x)=|x|. When you are graphing this you start at point (0,0). If you want to move the function left or right on the x-axis, it is called a transformation. And if you want to move the function up or down on the y-axis, it is called a translation. For example: I want to graph f(x)=|x|+5. This would be a translation because the function moved 5 places vertically. Another example is if I wanted to graph f(x)=|x+8|. this would be a transformation, because the function moved 8 places horizontally. When you want to graph refections there will always be a negative sign(-) before the absolute value sign(|x|). This reflects the function across the x-axis.
