1.What is function?

 

Answer:

Function is a relation where the first elements x of each ordered pair (x, y) are not repeated.

Step-by-step explanation:

Examples of ordered pairs of a function:

{(2,3), (3,4), (4,5) }

The first elements are 2, 3, 4.

The second elements are 3,4,5.  

A second element may be repeated but not the first element to be considered a function.
