# Function Calculator (Table of Values)

## Find Equation from Values

### How to calculate the values of a function?

The value (or image) of a function $f (x)$ is the value of the function $f$ for a given value of $x$.

Example: $f (x) = 3x$ then for $x = 2$ the value of $f (2) = 6$

The calculation of the values can be done on the entire domain of definition of the function. Any calculation of a value outside the definition domain will result in an error.

The totality of the values can be represented in a form of curve which is the graphical representation of the function.

### How to calculate the preimage of a value?

dCode has a tool to calculate the preimage by a function, ie the values of $x$ for which the function has a given value.

### How to apply a function over a whole table of value?

It is common to want to apply a function to a variety/sequence/list of values, such as an Excel column. Specifying the mathematical function to apply and dCode will calculate all the values automatically.
