How do i graph the function y^2=x*(x4)^2. I have no idea where to begin.

Y^2 = X(X4)^2.
Let X = 0:
Y^2 = 0(04)^2 = 0,
Y = 0.
Let X = 1:
Y^2 = 1(14)^2 = 9,
Y = sqrt9 = + 3.
(0,0),(1,+3),(2,+3.46),(3,+1.73),
(4,0),(5,+2.24).
Let X = 5:
Y^2 = 5(54)^2 = 405,
Y=sqrt(405) = sqrt(405*1) =+ 20.1i.
(5,+20i),(4,+16i),(3,+12.1i),
(2,+8.49i),(1,+5i).
i = imaginary = sqrt(1).
