Answers to Questions
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 column of value?
It is common to want to apply a function to a variety of values, such as an Excel column. Specifying the mathematical function to apply and dCode will calculate all the values automatically.
