Question

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


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

I think is c!

Answer 2

Nope.

Answer 3

why not?

Answer 4

The rule is that no x inputs can equal the same y-output.

Answer 5

This rule is violated in both tables:
A: 3->0 2->0
B: 3->-2 5->-2

Answer 6

So its b?

Answer 7

Yep

Answer 8

one more!

Answer 9

Please i do not understand it!

Which of the following equations best represents the graph of a function f(m)?

f(y) = m

f(x) = m

y = f(m)

x = f(m)

Answer 10

you still there?

Answer 11

y = f(m)
m is like x and y is the output, although this is a abad question because a person could assign any variable to the output so it could technically be x = f(m) too.
