Hello!
We can go through the choices and see if they are true
Choice 1
A function has one output for every input
This is not a function because it has -1 as an output for both 4 and -1
This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's
We see that the inputs are -1, 0, 3, and 4
This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's
We see the outputs are -2, -1, and 1
This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are
(-1, 1), (0, -2), (3, 1), (4, -1)
This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer
The answer is A) The diagram represents a function
------------------------------------------------------------------------------------------------------
Hope this helps!
