Graphing Functions

In the Graphing view, tap Tools

and go to Graph Entry/Edit > Function.

Type an expression for the function.

Manipulating a Function by Dragging

Linear Function

•

To translate, grab near the middle of the graph, and then drag.

•

To rotate, grab near the ends of the graph, and then drag.

Quadratic Function

•

To translate, grab near the vertex of the graph, and then drag.

•

To stretch, grab away from the vertex of the graph, and then drag.

Sine or Cosine Function

•

To translate, grab near the axis of vertical symmetry of the graph, and then drag.

•

To stretch, grab away from the axis of vertical symmetry of the graph, and then drag.

Finding Points of Interest on a Function Graph

▶

Create a point on the graph, and then drag the point to quickly identify maximums, minimums, and zeros.

Temporary signposts appear as you drag through the points of interest.

▶

For other points of interest, tap Tools

, select Analyze Graph, and select the type of analysis, such as Integral. The application prompts you to choose a graph and define the boundaries.
