Question

Complete this table so it shows a relation 7 3 4 8 3

Answer 1

In order to be a function, each input must have only one output value,

If an input value has 2 output values, it's not a function.

So, we can repeat any input number to make it not a function.

For example:

4

Now input 4 hast 2 output values , 8 and 9. therefore is not a function
