Solution 34798: Graphing a Function on the TI-84 Plus C Silver Edition Graphing Calculator.

How do I graph a function on a TI-84 Plus C Silver Edition?

The function graphing mode will graph equations in the format of y in terms of x. Therefore, equations will need to be solved in terms of y before being entered into the unit. The example below will demonstrate how to graph a function on a TI-84 Plus C Silver Edition graphing calculator.

Example:

Graph y - x = -3

Solution:

• First, solve for y. This is done manually using algebra.
• The new equation is: y=x-3.

To graph the equation:

• Press [Y=].
• Press [X] [-] [3] on the top line after Y1=.
• Press [GRAPH].

The graph will now be displayed on the screen.

Please see the TI-84 Plus C Silver Edition guidebook for additional information.
