Question

which graph does not represent a function?

Answer 1

the first and the 3 rd graph does not represent a function

Answer 2

Function:-

• Function is correction of data such that for every input value there are only one output.

• If for any input value there are more than one output value, it can not be a function.

• It can be understand by taking:

        Y = F(X)

        Here X is input value.

        While Y is output value for corresponding value of X.

For criteria of function:

• If there are one value of Y for any value of X, it will be function.

• If there are more than one value of Y for any value of X, it will not be function.

Now come to question:

• Graph A: There are only one value of Y for every value of X , So it is a function.

• Graph B: There are maximum two value of Y for every value of X , So it is not a function.

• Graph C: There are only one value of Y for every value of X , So it is function.
