When you have finished entering the equations, press the button.Īs soon as this button is pressed, your calculator will get to work drawing your equations on the graph screen! Now that you have entered your equations into the calculator, let’s see what they look like! You can navigate around using the arrow keys. You can graph up to 10 equations at a time, by typing them into each of the slots listed on the Y= screen. Keep in mind that all of your equations must have the Y term isolated on one side.įor 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”. Notice that I am not typing in the “y=” part, as the calculator does that for us (Y1=, Y2=, etc). To type the “X”, press the button on your calculator. So, for example, if I wanted to enter the equations y=4x+3 and y=x^2+3, I would do it like this: (using the arrow keys to switch to different equation slots) This is where you are able to enter all of the equations that you would like to graph. Entering Your Equationsīefore you can graph anything, you will need to type your equations into your calculator. This includes the TI-84 Plus, TI-84 Plus Silver Edition, TI-84 Plus C Silver Edition, and TI-84 Plus CE calculators. This guide will show you everything you need to know about graphing equations, and applies to every model of the TI-84.
However, despite it being easy to learn, it is not immediately obvious how to find and use this functionality. You would think that it would be easy to graph an equation/function on a graphing calculator.
