Question

State whether set of ordered pairs represent a function

{(-13,4) , (7,-15), (-13,9) (6,-12) (-18,0)

Answer 1

No, the given set of pairs does not represent a function

Explanation:

For a set of values to be a function, each input must have one and only one output value

Now, for the given set, we can note that:

The input -13 has two output values; 4 and 9

Therefore, this set is not a function

Hope this helps :)
