Evaluating a Function

Evaluating a Function

Enter your own function below in graphing calculator format (examples at the end of this page), enter value(s) for x (if needed; you can use the Tab key to move from cell to cell) and press the "Value of f(x)" button. Answers are rounded to 13 significant digits.

f(x) =
Value of x
Some Examples:
Expression 		Format (spaces are ignored)
2x 4
2*x-4   or   2x - 4
32
 3^2  or   pow(3,2)
3x2 + 4x 5
3*x^2+4*x-5   or   3x^2 + 4x - 5
3,000e2x-1
3000*e^(2*x-1)   or   3000*exp(2x-1)
2x 1

3x2 4x
(2x-1)/(3x^2 - 4x)
|2x ex|
abs(2x-exp(x))  or  abs(2x-e^x)
ln |4x35x| + log(10x)
ln(abs(4x^3-5x)) + log(10^x)
sin(x 4)
sin(pi*x-4)   NOT   sin(pix-4)
