Graphing Functions

1. In the Graphing view, tap Tools  and go to Graph Entry/Edit > Function.

2. Type an expression for the function.

3. Tap enter to graph the function.

 

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.

 

▶ 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.
