Unit 6 Test Questions

Boys won both games today.  We play in the Championship tomorrow vs Panhandle at 4:00.  Since we got in late tonight, I am only going to post one question.  Feel free to comment or ask questions.

Greg is looking at the graph of a parabola. Its vertex is (2, -144), it intersects the

x-axis at -4 and 8, and it intersects the  y-axis at -128.

What are the roots of the equation he has graphed?
