Overview:

Find domain and range from a graph, and an equation. Give the domain and range of the toolkit functions. Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the xx-axis. The range is the set of possible output values, which are shown on the yy-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.

Type of Material:

Development Tool

Recommended Uses:

The material would be well suited to use for in-class demonstrations or individual exploration, review or investigation, but could also be incorporated into a homework assignment.

Technical Requirements:

Any browser

Identify Major Learning Goals:

The main goal of this site is to aid users in visualizing the domain and the range of functions and their graphs, to determine the domain and range by using the interval notation, and to graph some of the parent functions.

Also, to provide users another way to identify the domain and range of functions is by using graphs

Strengths:

This Domain and Range applet is interactive and user friendly. Users can display the the graph of functions and can determine the domain and range by using the interval notations. This visual demonstration will be quite beneficial to many algebra students. Users can graph different functions and determine their domain and range. The tutorials and examples are helpful.

It provides a complete demonstration of the concept.

Concerns:

Could use complicated Functions fo more practice.

Potential Effectiveness as a Teaching Tool

Rating:

Strengths:

This applet is a great tool for helping students to visualize domain and range of functions and their graphs, and it is providing examples, videos, graphs, and exercises.

This is a helpful site for a quick refresher or for individual study. This would be a great resource to post in a course for students to review. It is a very efficient material.

Ease of Use for Both Students and Faculty

Rating:

Strengths:

This applet is easy and clear to use, and is engaging the user very well.

This allows users a chance to work through the examples on their own and learn in a didactic way.

Concerns:
