UNIT
9
9.3: Match a Quadratic Equation to its Graph
21.0: Students graph quadratic functions and know that their roots are the $$x$$-intercepts.
22.0: Students use the quadratic formula or factoring techniques or both to determine whehter the graph of a quadratic function will intersect the $$x$$-axis in zero, one, or two points.
23.0: Students apply quadratic equations to physical problems, such as the motion of an object under the force of gravity.

## Today's Objective

Students will be able to create a quadratic equation from its graph using the roots.
