  1. Rewrite as a piecewise function.

    Notice how this graph differs from . From this we can determine that there will be three pieces, and we already know the first and last piece.

    The middle piece is a vertical reflection of .

  2. Using set notation, state the domain and range of .

    Consider how the range of differs from the range of .

  3. Estimate by any method.

    A trapezoidal sum is an option.

  4. Write a Riemann sum to approximate with rectangles of equal width and evaluate the sum.

    The height is determined by the function.
