inputs, the machine, outputs, point

input x, the machine squares it and gives out y ... ( x, y )

input -2, the machine squares it and gives out 4 ... ( -2, 4 )

input -1, the machine squares it and gives out 1 ... ( -1, 1 )

input 0, the machine squares it and gives out 0 ... ( 0, 0 )

input 1, the machine squares it and gives out 1 ... ( 1, 1 )

input 2, the machine squares it and gives out 4 ... ( 2, 4 )


This gives us the set of points for Standard Parabola Guy:
