The values you enter will be the left and right lengths of the X axis. By default this will be set at 1, this means that there will be a tick mark for every 1 X value on the graph. Below, the image on the left has 40 tick marks on each axis, the image on the right has 20 tick marks per axis. This means basically means how many actual points the calculator will plot to make the line. If you graph a line with a low resolution setting by entering a larger number , it will look like the parabola on the left below.
It will graph super quickly but also be more jagged. If you graph a line with a higher resolution by entering a lower number , the line will be more sooth but it will graph slower because the calculator has to calculate more points. Finally if you want to easily reset the window size, there is a way to do that too. If you want to reset your window just scroll to that option and press [enter]. I need help , my TI 84 plus CE calculator is not working.
What need to be done? There is a way to reset your calculator without losing your programs. Your email address will not be published. Notify me of new posts by email.

The domain certainly excludes any x values where there are vertical asymptotes.
Horizontal asymptotes are usually obvious. Always do some algebra work to confirm the asymptotes. The x value must be within the current viewing window. Then adjust your viewing window and try again. You can trace along the graph to find any intercept. The intercepts of a graph are where it crosses or touches an axis:. You can plot multiple functions on the same screen. This is equivalent to solving a system of equations graphically.
As always, you should confirm apparent solutions by substituting in both equations. Updated for grid properties of color TIs here , here , and here. Explained the meaning of Xres , and the meanings of the two extra window parameters for color Ts. Supplied missing words in the instructions for adjusting the grid boundaries.

You need to look for any previously set plots that might interfere with your new one. Look at the top of the screen. No information is lost; you can always go back and reactivate any plot. Sometimes you might want to graph more than one function on the same axes. My screen looked like this after I deactivated all old plots and functions.
Check your function and correct any mistakes. To delete any extra characters, press [ DEL ]. Press [ ZOOM ] [ 6 ]. Locate an x intercept by eye.
You select 2:zero because the x intercepts are zeroes of the function. Graph both functions on the same set of axes. Zoom out if necessary to find all solutions.
