You are to demonstrate that you understand what represents a function and what does not represent a function. you may do this by either writing a paragraph using complete sentences or drawing pictures with labels.

For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.

We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
