To be a function a line has to pass the vertical line test

atsie · Answer

Oh I forgot that it has to be drawn on a graph first.

Which one of these lines doesnt pass the vertical line test

atsie · Answer

Quite frankly, it gives the appearance that all of them don't. But wouldn't it be A? Because its going vertical and only passing through one line? @legomyego180

legomyego180 · Answer

Sorry, its not easy using these things to draw
Yup A.
So line A is X=some number because x=any constant will always be a straight line, and therefore never be a function.

atsie · Answer

Ooh, so it's x only then right? @legomyego180

legomyego180 · Answer

So you have one relation that is an "undefined" line. Therefore yes A would be your answer BECAUSE when taking a pencil and moving it vertically across your paper/graph, you will see that it covers the whole line.

Thanks for confirming Rebecca. ^.^
Also thank you to @legomyego180 .
I appreciate it! :)

http://prntscr.com/b5bk4z example of relations that are NOT functions. They would hit more than one point.

Its just really crazy hard for me to decipher the points, but hopefully I'll learn eventually. I'm just super slow and dumb. XD  @rebeccaxhawaii
