              Solving Quadratic Equations Graphically

              There are several examples for the teacher to demonstrate solving quadratic equations graphically.  Students will need to be competent in plotting straight line graphs and quadratic functions.
              Differentiated Learning Objectives
              • All students should be able to use graphical methods to solve the roots of a quadratic equation.
              • Most students should be able to use a linear function to solve a quadratic equation graphically.
              • Some students should be able to derive and solve the resultant quadratic equation from linear and quadratic graphs.
