TI-84 Graphing Calculator
I greet you this day,
Please solve the questions on your own before checking your answers with the calculators.
I wrote the codes for some of the calculators using JavaScript, a client-side scripting language.
The Wolfram Alpha widgets (many thanks to the developers) were used for some calculators.
Comments, ideas, areas of improvement, questions, and constructive criticisms are welcome. You may contact me.
If you are my student, please do not contact me here. Contact me via the school's system.
Thank you for visiting.

This calculator will:
(1.) Graph a polynomial function.
To use the calculator, please:
(1.) Type your function/expression in the textbox (the bigger textbox).
(2.) Type it according to the examples I listed.
(3.) Delete the "default" function/expression in the textbox of the calculator.
(4.) Copy and paste the expression you typed, into the small textbox of the calculator.
(5.) Click the "Submit" button.
(6.) Check to make sure that it is the correct function/expression you typed.

Graph
This calculator will:
(1.) Determine the symmetry of a function (as indicated by Result: and/or Parity relation: in the output window).
(2.) Determine other details regarding the function.
To use the calculator, please:
(1.) Type your function (equation) or expression in the textbox (the bigger textbox).
(2.) Type it according to the examples I listed.
(3.) Copy and paste the function (equation) you typed, into the small textbox of the calculator.
(4.) Click the "Submit" button.
(5.) Check to make sure it is the correct function or expression you typed.
(6.) Review the answer.
Function:
This calculator will:
(1.) Determine the inverse of a function.
(2.) Graph the function.
(3.) Graph the inverse of the function.
The function and the inverse of the function are plotted on the same graph.
To use the calculator, please:
(1.) Type your function (equation) or expression in the textbox (the bigger textbox).
(2.) Type it according to the examples I listed.
(3.) Copy and paste the function (equation) you typed, into the small textbox of the calculator.

(6.) Review the answer.
Function:
This calculator will:
(1.) Calculate the difference quotient of a function.
(2.) Return the answer in the simplest form.
To use the calculator, please:
(1.) Assume the function is $f(x)$.
(2.) Assume the function value is $f(x + h)$.
(3.) Calculate the function value first. Use the "Evaluating Functions Calculator" to calculate it.
Find the value of $f(x + h)$ first using the "Evaluating Functions Calculator".
In other words, evaluate the function, $f(x)$ for $x = x + h$ using the "Evaluating Functions Calculator".
(4.) Type your expression in the first textbox: bigger Textbox 1.
(5.) Type the result (the calculated value you got from the Evaluating Functions Calculator) in the second textbox:
bigger Textbox 2.

$f(x + h)$:
Please NOTE:
(1.) If any of the answers is a decimal, and you want to convert it to a fraction, please use the calculator in this tab
that converts decimals into simplified fractions.
Just copy the entire decimal (without the sign) as is and paste in that calculator.
Then, you can include the sign if it is a negative sign.
Please NOTE:
(1.) If none of the $x-coordinates$ of the points is zero, please put the lesser value of $x$ as the $x-coordinate$
of Point $1$ along with it's matching $y-coordinate$ (not necessarily the lesser $y-coordinate$).
(2.) If any of the answers is a decimal, and you want to convert it to a fraction, please use the calculator in this tab
that converts decimals into simplified fractions.
Just copy the entire decimal (without the sign) as is and paste in that calculator.
Then, you can include the sign if it is a negative sign.
(3.) If there are any decimals in the Slope-Intercept Form, then the Standard Form will not be
correct.
What do you need to do?
Please convert the decimals into simplified fractions.
Then use the appropriate forms in this tab to convert the Slope-Intercept Form to Standard Form
Please NOTE:
