## Solution 34798: Graphing a Function on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.

### How do I graph a function on the TI-83 Plus and TI-84 Plus family of graphing calculators?

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 the TI-83 Plus and TI-84 Plus family of graphing calculators.

Example:

Graph y - x = -3

Solution:

• First, solve for y. This must be done manually by hand using algebra because the TI-83 Plus and TI-84 Plus family of graphing calculators are not CAS calculators.
• 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-83 Plus and TI-84 Plus Family guidebooks for additional information.
