Corespondenta dintre numele si prenumele oamenilor defineste o functie? justificati

Correspondence between name and family name defines a function? Justify.

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value because it depends on the value of the input.

Correspondence between a name and a family name does not define a function.

Because there can be many output in a single input.

For example:

Input Output

Name Family Name

Jennifer Lopez

Lawrence

Hudson = = as you can see, there are many outputs in a single input. It is not a function.

Input Output

Family Name Name

Obama Barack

Michelle

Malia = not a function, single input, numerous output

An example of a function is:

Name of President Name of Country

Barack Obama USA

- only one country corresponds to that name of the president.

However, if we interchange it. It will not be a function because there are a lot of names of presidents in the country USA.
