Lesson: Domain and Range of a Function Mathematics • Second Year of Secondary School

In this lesson, we will learn how to identify the domain and range of functions from their equations.

Lesson Plan

Students will be able to

recall the definitions of the domain and the range of a function,
identify the ordered pairs of a function given the domain, range, and equation of the function,
identify the range of a function given the domain and the equation of the function,
identify the domain of a function given the range and equation of the function,
identify the domain and range of a discrete function and mapping diagram,
identify the domain and range of a function given a graph of the function,
identify the domain and range of a function given the equation of the function.
