Question

Is the following relation a function?


{(1, -2), (1, -3), (2, 1), (3, -2)}

Yes or no

pls help me

Answer 1

a function is a set of ordered pairs where no two 2nd elements are related to the same 1st element.

So, it is not a function if more than one pair have the same 1st element.

Look at the numbers and you can get the answer.
