Tables, Equations

In this video lesson, students work with graphs and tables that represent functions. They learn the conventions of graphing the independent variable (input) on the horizontal axis and the dependent variable (output) on the vertical axis and that each coordinate point represents an input-output pair of the function. By matching contexts and graphs and reading information about functions from graphs and tables, students become familiar with the different representations and draw connections between them.
