A Function Calculator is a free online tool that displays the graph of the given function. In the subject of algebra, a function has been defined as an equation which assigns exactly one and one only output for every given specified input. It is most generally and commonly described as a function of f(x).

A function has been suggested to be a mathematical rule that defines the relationship between the dependent and independent variable. Mostly, all the mathematical formulas are expressions of some known function.

Accordingly, the graph of the function can graphically be represented by calculating the numerical values of the x-intercept, the y-intercept, the slope value and the curvature value.

The standard form to represent the function is given under:

F (x) = y

Here, “x” represents the input, “f” represents the function, “y” represents the output of the desired function.

The procedure to use the function calculator is as follows:

Step 1: Begin with entering the function f(x) in the given input value field.

Step 2: Now, you need to hit the button “Graph” in order to get the output.

Step 3: Finally, the graph of the function will be displayed in a new tab.
