To answer this problem, you use each value of x,solve for y, and check if it agrees to the specified answer above.

x = 0: y = 5(0)^2 = 0 => (0,0)
x = 2: y = 5(2)^2 = 20 => (2,20)
x=3: y = 5(3)^2 = 45 => (3,45)
x=5: y = 5(5)^2 = 125 => (5,125)

The incorrect value is for x=2. The correct coordinates should be (2,20).
