Investigation 6: The Graph of

• The graphs of f(x) and and are identical for the intervals where
  f(x) > 0.
• The graphs of f(x) and and are different over the intervals where
  f(x) < 0. The parts are actually reflection images of one another in the x-axis.
• To graph the graph of from the graph of f(x), take the portion of the graph that is below the x-axis and reflect it across the axis.
