Answer 2

a function has for each input only 1 output

the input is x

the output is y

Answer 3

ok

Answer 4

does that help or no?

Answer 5

not really

Answer 6

look at B for example.

it has the input of 9 and the output of 0,
9 is the x value, 0 is the y value

it also has for the input of 9 the output of -8,
9 is the x value, -8 is the y value

Answer 7

so that has an input which gives two different outputs

Answer 8

ok so b is not possible

Answer 9

correct, B is not a function

Answer 10

so then A?

Answer 11

Answer 12

yes, A is correct, nice :)
