The graph of y = SQRT(x3 - x) contains which point?
Try the value given for x, see if it equals the value given for y
The first one 3, 24

the square root of 24 is between 4 and 5, so this is not the answer
:
Do the same with each answer
E is the correct one, where x = 4

factor inside the radical to reveal a perfect square (4)

extract the square root of that and you have

:
I am not sure about this 2nd equation, does not make sense
