In this lesson, we will learn how to graph a quadratic function of the form 𝑓(𝑥)=a𝑥²+b𝑥+c, in order to solve the equation 𝑓(𝑥)=0.

Students will be able to

understand that, for a quadratic function of the form
- the solutions to the equation occur where the graph intersects the ,
find the solutions to the equation
- when given the graph of ,
- when points of the form that lie on the graph are specified,
- by plotting the graph of over a specified interval.
