Solving Quadratic Equations Graphically

 

Students learn how to estimate the solutions to a quadratic equation using graphs.

As learning progresses, they model real-life problems graphically.

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 resulting quadratic equation from linear and quadratic graphs.
