Best ResponseYou've already chosen the best response.0if we use the vertical line test, dw:1444447025149:dw etc, we see that the relation is not a function since it must intersect a xcoordinate at only one ycoordinate

Best ResponseYou've already chosen the best response.0if we put a vertical line at say x=3 , then the line intersects two points.

Best ResponseYou've already chosen the best response.0since the vertical line intersects the relation twice, then it is not a function. perhaps look at this link http://www.regentsprep.org/regents/math/algtrig/ATP5/LFunction.htm
