Lesson: Graphing Simple Quadratic Functions Mathematics

In this lesson, we will learn how to graph and interpret quadratic functions of the form 𝑦 = 𝑘𝑥² + 𝑐.

Lesson Plan

Students will be able to

complete a table of values for a quadratic function of the form ,
sketch a graph of a quadratic function of the form using a table of values given an interval over which to graph,
identify the equation of a quadratic function of the form given its graph,
identify what happens to our graph when we change the values of the constants in our function.

Q1:

Write the quadratic equation represented by the graph shown.

Q2:

Which of the following graphs represents the equation ?

Q3:

Which of the following is the equation of the function drawn on the graph?
