Function definition.... at one point, it won't give two value, means for one x value, it won't give two y value ..just remember this point and using this to answer all graphical questions...

1st row

1st graph yes it represents function because nowhere it violets the definition of function....

2nd graph yes it represents function because nowhere it violets the definition of a function...

3rd graph NO it does not represents function because at one point it violets the definition of function... for x=0 , it gives two 'y' value, one is +1 and other is '-1' ...

2nd row...

1st graph NO it does not represents function because at every point almost it violets the definition of function...and gives two y values for a single value of x....

2nd graph yes it represents function because nowhere it violets the definition of a function.

3rd graph NO it does not represents function because at two point it violets the definition of function... at x=-2 and at x=5 it gives two y values...
