Question

What is the definition of function?

  1. Has inputs and outputs    
  2. Every input has only ONE output    
  3. Inputs have different outputs every time    
  4. x-values and y-values    

hintHint:

General definition of  a function.

The correct answer is: Every input has only ONE output


     * Function is generally represented as f space colon space X rightwards arrow Y. Then, we can write the statement that f is a function from X to Y.
    ** Hence, A function is more formally defined given a set of inputs X(domains) and a set of possible outputs Y(codomain) as a set of ordered pairs (x, y). 
    *** Hence, we can say that if the object x is in the set of inputs then a function f will map the object x to exactly one object f(x) in the set of possible outputs.  
    *** Hence, we can say that for a function there exists a different output for any input.

    Let us consider a function that defined as f space colon space X rightwards arrow Y. then, the representation may exist as shown below.
    func-diag (y=sqrt x)
    Hence, Every object x that belongs to the set of inputs has exactly one object y that belongs to the set of outputs.
    *** Hence, the technical definition of the function is a relation from a set of i9nputs to set of possible outputs where each input is related to exactly one output.
