State whether set of ordered pairs represent a function {(-13,4) , (7,-15), (-13,9) (6,-12) (-18,0)

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

Step-by-step 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

Hope this helps :)
