This utility will evaluate and graph your function of a single variable. Simply specify your function as a mathematical expression in the text box below, then proceed to evaluate or graph. To evaluate for a given argument value, specify the value and click the "evaluate f(x)" button. The function value for that argument will be calculated, and the value's step-by-step derivation will be displayed. To generate a graph of your function, specify the desired argument range, and optionally the function output range (on the vertical axis) to display, then click the "graph f(x)" button.
You also have the option to evaluate or graph up to five different functions simultaneously. Click on the "Add another function" button to increase the number of functions.
