Curve, starting from upper left, turning at the approximate points (negative 2.25, comma negative 35), & (0.25, comma 25) & the exact point, (2, comma 0) & continuing up & right, passing through the exact points (negative 3 comma 0), & (negative 1, comma 0).Write a possible equation for the graph at right.  

If is a root (-intercept), then is a factor in the equation of the function.

  1. Explain how you can decide if your equation represents the graph. What can you do to the equation to make it a better fit for the graph if needed?

  2. The graph goes through the point . Use this information to test the accuracy of your equation and make adjustments if needed.
