Exploring Quadratic Functions

Let's begin by exploring various graphs and equations. By studying the attributes of the examples and non-examples, you should be able to

identify graphs of quadratic function

identify equations of a quadratic function

define a quadratic function

describe the characteristics of a quadratic function


The following functions are NOT quadratic functions:








The following ARE quadratic functions:






Based on the graphs above, DESCRIBE several characteristics of a quadratic function.


The following are NOT equations of quadratic functions:







The following ARE equations of quadratic functions:






Describe the difference between the examples and the non-examples of these equations:



Now try to define a quadratic function using both parts of this exploration:
