Question

Does the relation shown below represent a function? Explain.

(2, 1), (1.-6), (6,-3). (4.-7)
The relation is not a function because

there is an output that
there is an input tha
each output
each input

Answer 1

To determine whether the relation shown below represents a function, we need to check whether each input value has a unique output value. If there is an input value that has more than one output value, then the relation is not a function.

The relation shown below is:

(2, 1), (1, -6), (6, -3), (4, -7)

We can see that the input value of 1 has two different output values: -6 and -7. Therefore, the relation is not a function.

I hope this helps answer your question!
