(2,6) (-3,6) (4,9) (2,10) how do I deteromine whether each relation represents function
.
Basically, you would be performing the "vertical line test" -- that is, for any value of x, there can only be one value of y.
In this case,
(2,6) (2,10)
there are TWO possible values of y when x=2.
.
So NO, this is NOT a function.
