Table B
x 3 5 4
y −2 1 1


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

for each to be a function, for each input value of X, there can only be one output value for Y

Answer 2

you cant have two different Y values for the same X value...

Answer 3

so .. they arent functions

Answer 4

yep

Answer 5

if you graph them, or have a graph,

Scan the thing with a vertical line, if it crosses more than one point at the same time , it is not a function

Answer 6

so would it be the second answer

Answer 7

meaning , it has 2 or more y values for the given x

Answer 8

They are both function, there arent any repeated X values for either
