Copy the table below on your paper and complete it for the equation . Then graph and connect the points on graph paper. Name the roots (x-intercepts).s).  

For ,

Make a graph by plotting the points from the table you have completed.



Look for the two points of the parabola that touch the -axis in order to find the -intercepts.

Now solve for in terms of the other values that have been given in the above table.


A parabola with points at (negative 4, 5), (0, negative 3), (negative 2, 3), (negative 1, 4), (0, negative 3), (0, 1), and (1, 5).

Does yours look like the graph above?
