An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...

The alternate method is to subsitute each point into each equations...
I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.
so eliminate A
repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.
That's why graphing is easier
