Question

The tables below show the values of y corresponding to different values of x:


Table A
x 3 2 1
y 1 0 0
Table B
x 3 5 5
y −2 1 2


Which statement is true for the tables?
Both Table A and Table B represent functions.
Both Table A and Table B do not represent functions.
Table A does not represent a function, but Table B represents a function.
Table A represents a function, but Table B does not represent a function.

Answer 1

What is a function?
A rule that must work for every possible input value
And it has only out put for each in put.....

@pupflower what do you think?

Answer 2

I think both tables don't represent functions

Answer 3

I agree with on B...the table doesn't represent a function because 5 has two outputs (not allowed)

However, A is a function.. Each x has it's own y. It is allowed for different x values to have the same y value
