Students explore how the constant of variation, k, affects the graph of direct and inverse variations.
Students explore the effects of a, the constant of variation. They will first use the Transformation Graphing app to change a and observe how the direct variation graph changes.
For the application problem about direct variation, students will use a graph of the function and a point on the graph to determine the amount of money the employee will make for a certain number of hours.
Students will investigate the effect of a on the graph of an inverse variation using the left and right arrow keys.
