Tool for calculating the different values of a function from its equation f(x) and given values in order to compute their images by the function calculator.

dCode is free and its tools are a valuable help in games, maths, geocaching, puzzles and problems to solve every day! A suggestion ? a feedback ? a bug ? an idea ? Write to dCode!

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.
