You would think that it would be easy to graph an equation\/function on a graphing <\/strong>calculator. However, despite it being easy to learn, it is not immediately obvious how to find and use this functionality.<\/p>\n\n\n\n

This guide will show you everything you need to know about graphing equations, and\u00a0applies to every model of the TI-84. This\u00a0includes\u00a0the TI-84 Plus, TI-84 Plus Silver Edition, TI-84 Plus C Silver Edition, and TI-84 Plus CE calculators.<\/p>\n\n\n\n

Entering Your Equations<\/strong><\/h2>\n\n\n\n

Before you can graph anything, you will need to type your equations into your calculator.<\/p>\n\n\n\n

Press the [y=]<\/strong> button on your calculator.<\/p>\n\n\n\n

\"Y=<\/figure>\n\n\n\n

You will now see the screen shown below. This is where you are able to enter all of the equations that you would like to graph.<\/p>\n\n\n\n

\"Y=<\/figure>\n\n\n\n

So, for example, if I wanted to enter the equations y=4x+3<\/strong> and y=x^2+3<\/strong>, I would do it like this: (using the arrow keys to switch to different equation slots)<\/p>\n\n\n\n

\"Equations<\/figure>\n\n\n\n

To type the “X”<\/strong>, press the [X,T,\u0398,n] <\/strong>button on your calculator.<\/p>\n\n\n\n

\"X,T,<\/figure>\n\n\n\n

Notice that I am not <\/strong>typing in the “y=” part, as the calculator does that for us (Y1=, Y2=, etc).<\/p>\n\n\n\n

Keep in mind that all of your equations must<\/strong> have the Y term isolated on one side.<\/p>\n\n\n\n

For example, if we had an equation such as Y+4=X, we would have to subtract 4 from both sides to get Y=X-4, so that we could type it into our calculator as “X-4”.<\/p>\n\n\n\n

You can graph up to 10 equations at a time<\/strong>, by typing them into each of the slots listed on the Y= screen. You can navigate around using the arrow keys.<\/p>\n\n\n\n

Graphing Your Equations<\/strong><\/h2>\n\n\n\n

Now that you have entered your equations into the calculator, let’s see what they look like!<\/p>\n\n\n\n

When you have finished entering the equations, press the [graph] <\/strong>button.<\/p>\n\n\n\n

\"Graph<\/figure>\n\n\n\n

 As soon as this button is pressed, your calculator will get to work drawing your equations on the graph screen!<\/p>\n\n\n\n

\"Graph<\/figure>\n\n\n\n

To change the equations<\/strong> you entered, just press the [y=] button again.<\/p>\n\n\n\n

To clear the equations<\/strong> you entered, press [y=], scroll to the equation you want to delete, and press the clear button.<\/p>\n\n\n\n

If you are unable to see the function you typed in, you may need to adjust your viewing window, as described in the next section.<\/p>\n\n\n\n

Adjusting the Viewing Window<\/strong><\/h2>\n\n\n\n

The best way to exactly set up the viewing window is to use the [window]<\/strong> button on your calculator (it is right next to the [y=] button).<\/p>\n\n\n\n

Upon opening it, you will see several scary-looking numbers. Thankfully, you have this tutorial to guide you. The following diagram should help you understand exactly what these numbers mean:<\/p>\n\n\n\n
