Sagot :

Among the following relations, the Function is option D,{1,2,2,3,3,4,4,5}.

In simple words, a function is a relationship between inputs where each input is related to exactly one output.  Functions are often defined by a formula that describes a combination of arithmetic operations

A function is uniquely represented by the set of all pairs (x, f (x)), called the graph of the function, a popular means of illustrating the function. To identify a function from a relation, we just have to see if any 'x' values are being repeated, if not, it is a function. If x values are repeated, and y values are different, then we have a relationship and not a function.

In the question, we can see that values 2,3, and 4 are repeating. This specifies that they are a function.
