3.2 Domain and range of a function
Domain and range of a function
The domain of a function is all the possible values of x’s of ordered pairs; whereas the range of a function is all the possible values of y’s of ordered pairs. You can easily find them by graphing the functions or ordered pairs. Let’s see how in this lesson.
Basic concepts:
 Draw on coordinate planes
 Horizontal and vertical distances
 Relationship between two variables
Related concepts:
