Hello,
I am afraid I am missing something here. You can start with the expression of a function and have it graphed on a graphing calculator.
Or you can enter the experimental data, represent them on a graphing calculator and ask the calculator to find the curve that fits the data best, and once that curve is found to give you the equation.
However your calculator does not have the graphing capabilities. All you can do is enter the data and ask the calculator to perform a regression to obtain the expression of the function that fits best.

The available options for the calculator are accessible by pressing [MODE][3:Stat] and
2. A+BX linear
3: _+cX^2 quadratic
4: ln X logarithmic
5: e^X exponential
6:A*B^X power
7: A*X^B Polynomial
8: 1/X

Hope it helps.

Is the graph of a circle a function?


No. The graph of a circle is a graph, one which can have two different values for certain arguments. The graph of the top or bottom half of a circle can be considered a graph of a function.

Graphing ellipse


This is not a graphing calculator. Besides, most graphing calculators are able to graph functions, and conics are not functions. You need a utility that graphs conics. The Casio FX-9750G and others have a conics utility. On the TI83/84 Plus you can download an application that draws them.

How to graph a function
Look for a key labeled Y= ( the y= editor) and press it. Use the key pad to type in the right side of the function.
Press Graph to display the graph.
If drawing is out of range set the window parameters. Alternatively (if there is a zoom key) use it to select a ZoomIn, a ZoomOut , Zoom Standard.

I try to graph an absolute value on my Ti 89 and I put the inequality in right but when I go to graph it my calculator says undefined variable.


If you want to graph the absolute value of a function, feed the function to the absolute value ie graph y= abs(f(x)). The calculator will take care of it. See screen captures where I draw the function y1=x^3-5x^2-3 and y2='x^3-5x^2-3'. On the first graph the function is represented and on the second the function and its absolute value.

The calculator knows how to calculate the absolute value of an expression. The name of the command is abs(

How do I get more than one graph to graph? The calculator is stopping me from turning more than one graph on.


After entering the first function to graph press the down arrow and when the cursor blinks after Y2 type in the second function you wish to graph. After you finished entering multiple functions make sure the graph setting under the window button are set correctly so every function will be visible at the interval you set. After that you hit Graph and you should see your graphs being plotted.


I hope it helps.

I have a TI-Nspire Graphic Calculator (Not the CAS.) I had a couple of questions about the calculator. First off, how do I limit the domain on a function that I am graphing. For example, I am graphing y=x...


simply divide the function by the domain you wish.

In your example, you wanted to graph y=x for x>=0.
You should graph the function f1=(x)/(x>0)

To find out when y=900, graph the function in f1, and then graph the equation y=900 (which will be a horizontal line) and use the intersect function to find where they cross. The x-coordinate of the intersection is the solution you are seeking.

How to use graphing calculator?


The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

  1. Most graphing calculators basically function the same way.
  2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
  3. You enter the algebraic form of the function you want to draw.
  4. You press a button or menu to GRAPH
  5. The graph is drawn.
  6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
  7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
  8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

I dont know how to graph


Hello,
Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.
An entry screen appears where you enter the functions you want to graph.
On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.
