The graph of is shown at right. Below are graphs of and , which are transformations of . Write equations for and in terms of .   

  1. This curve has been vertically reflected.
    A vertical reflection of results in a ray of on the right side. How does that compare to this curve?

  1. This curve has been vertically stretched.
    The "bounds" of are and , so think of the "height" as units.
    How does this compare to the "height" of ?

    If is vertically stretched by a factor of , the point where the curve bends, will end up at . Where is this point on ?
    Add "shifts" to your equation.
