Best ResponseYou've already chosen the best response.1Every unput (x value) must have a unique output (y value) for a relation to be considered a function. The vertical line test can be used to determine if a relation is a function. If you can draw a vertical line that goes through a relation more than once it is a function This is a function by the vertical line test: dw:1435352050788:dw This is NOT a function by the vertical line test: dw:1435352079662:dw It fails the vertical line test, a line can pass through it more than once

Best ResponseYou've already chosen the best response.1graphing would be the safest bet, but you could also consider think about what I wrote: Every input (x value) must have a unique output (y value) for a relation to be considered a function. Ask yourself: Are there two points with the same x coordinate with a different y coordinate in your relation. Which point would cause the function to fail the vertical line test?

Best ResponseYou've already chosen the best response.1just to be clear: The graphs I did the vertical test on were as follows, the line I drew on top of them was the test itself: dw:1435352616053:dw dw:1435352637672:dw

Best ResponseYou've already chosen the best response.0(4,3) and (4,5) have the same x value
