Interactive, free online graphing calculator from GeoGebra: graph functions, plot data, drag sliders, and much more!

Deduce the criteria for directly proportional, linear, or nonlinear relationships by manipulating the graph of a line.

This is a one-to-many relationship. This graph should be used as a non-function example.

By the end of this lesson, you should discover on how to graph and interpret logarithmic functions.   We can use one cartesian coordinate system in graphing one or more logarithmic functions to …

The following applet was designed to help you see the relationship between the equation of a circle and its graph. Adjust the sliders "h", "k", and "r" (one at at time), and observe what happens to the graph …

Identify linear and nonlinear relationships in scatter plots. View trend lines when there is a relation between the points.

Given a proportional relationship represented by tables, graphs, models, or algebraic or verbal descriptions, identify the unit rate (constant of proportionality)

Visualize equations and functions with interactive graphs and plots Explore geometric concepts and constructions in a dynamic environment Perform calculations with fractions, statistics and …

Choose a graph to trace: Sine, Cosine, or both Click on Start Animation to begin or stop the trace. You may also drag the orange point around the circle to manually trace the curves.

Based on the previous graphs and the graphs of and below, can you make a general conjecture about the graph of a function and its inverse? Test your conjecture by inputting functions in the graph below …
