1. Begin by sketching the graph of y=lxl. Then use transformations of this graph to graph y= lx -2l +1. Show all your work. (Step by step transformations, labeling each graph along the way.)

2. Let f(x) = 3x and let g(x) = x-1. Find (f+g)(x) and (fog)(x) and (fog)(2).

3. Let f(x) = 4x+1. Find f-1(x).
