Function refers to a relation or expression involving one or more variables. In a function each value of x corresponds to each value of y. A relation which is having two or more values of y for x values is not a function.
We have been given points (-2,-5), (-1,3), (1,-2) , (3,0) ,(4,-2) (4,4).
These are not points of a function because of a simple reason that it has two values of y for each one value of x.
Value of relation at x=-2 is -5.
Value of relation at x=-1 is 3.
Value of relation at x=1 is -2.
Value of relation at x=3 is 0.
Value of relation at x=4 is -2.
Value of relation at x=4 also equal to 4.
It has two values at x=4 one is -2 and other one is 4.
Hence the relation is not a function because there are two different y-values for a single x-value.
