(x2)2=y(y1)2(x-2)^2 = y(y-1)^2

Let the point on the curve with respect to old axis is (x,y)

Let the same point on the curve with respect to new axis be (x ′ ,y ′ )

The new co-ordinates are shifted by (2,1) Thus x=x ′ +2 and y=y ′ +1

Replacing the value of x and y in (x2)2=y(y1)2(x-2)^2 = y(y-1)^2 ,we get

(x+22)2=(y+1)(y+11)2(x)2=(y+1)(y)2(x'+2-2)^2 = (y'+1)(y'+1-1)^2\\ (x')^2 = (y'+1)(y')^2

answer: (x)2=(y+1)(y)2(x')^2 = (y'+1)(y')^2
