Answer 5

Do you know what the vertical line test is?

Answer 6

do you know what a function is

Answer 7

I think it's either A or C

Answer 8

A function can not have to points on a vertical line.

Answer 9

oh, so its not C...

Answer 10

So A is ruled out because it is a vertical line, a function is NEVER a vertical line.

Answer 11

yeah

Answer 12

yes it can be c

Answer 13

what about Horizontal?

Answer 14

C is diagonal not verticle

Answer 15

oh...

Answer 16

horizontal is also allowed in a function

Answer 17

B, doesn't have a line at all.

Answer 18

So if you draw a line to connect ALL the dots on B and D will there be any verticle lines?

Answer 19

If there are than that means they are not functions
