Respuesta :
For a function a x value cannot have more than 1 corresponding y value
So for example, A, has the x value 1 which has the y values 1 and 5, so because it has multiple x values it is not a function.
So the answer is C
This can be proved because,
8 only has one corresponding y value (-1)
7 only has one corresponding y value (2)
6 only has one corresponding y value (-1)
5 only has one corresponding y value (2)
and 4 only has one corresponding y value (-1)
Each x factor has a unique y factor, making answer choice C a function.

The table which represents y as a function of x from the options given is table C.
To write, y as a function of x ;
y = f(x)
This means that the value of y depends on the value passed in for x.
This means that the value of y for a particular x value cannot change.
Using this explanation to evaluate the data tables given.
Table A :
The values of y for x = 1 are (1 and 5) ; this is not unique.
Table B :
Values of y for x = 4 are - 6 and - 4 (not unique)
Table C :
The given values of x are all distinct
Table D :
For x = 3 ;
y values are not unique, with values 0, 2 and 3 obtained for a single value of x.
Hence, the table which represents y as a function of x is table C.
