Best ResponseYou've already chosen the best response.0Lines on graphs can be functions. And it isn't a line on a graph. Try again. (it is not a function)

Best ResponseYou've already chosen the best response.0wait how is this not a function? if you divide by 7 (to get the values you x to equal y by itself) then you get the absolute value of 9/7 x equals the absolute value of y. that means that its just and absolute value graph which IS a function

Best ResponseYou've already chosen the best response.0No, as newton said, for x = say 7, both y= +9 and y = 9 solve the equation. thus, one value of x maps onto two values of y. Therefore this is not a function.

Best ResponseYou've already chosen the best response.0since, with an input value, x, we cannot determine the output, y, this is not a function.
