2010	5000
2012	6000
2014	7000
2016	8000

State Yes/No
Does the above table represents No. of bikes as the function of years in which these are produced.

Answer 1

If function is shown in tabular form there should be one Input value colum and other output valuen column. And every element in the Input value column should be associated with unique element of Output value column.

Now, in the given table let us take YEAR column as the input value column and No. OF BIKES column to be the output value column. Also we can see that every element of YEAR column is associated with the unique element of No. OF BIKES column so we can say that the table represents No. OF BIKES as the function of YEAR.
