Question

Which explains why the graph is not a function? It is not a function because the points are not connected to each other. It is not a function because the points are not related by a single equation. It is not a function because there are two different x-values for a single y-value. It is not a function because there are two different y-values for a single x-value.On a coordinate plane, solid circles appear at the following points: (negative 2, negative 5), (negative 1, 3), (1, negative 2), (3, 0), (4, negative 2), (4, 4).

Answer 1

The given points of the expression is not a function because there are two different y-values for a single x-value.

Given The points are : (-2,-5), (-1,3), (1,-2) , (3,0) ,(4,-2) (4,4)

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.
