The vertex of the parabola y^(2) =(a-b) (x-a) is :

Answer»

(b, a)
(a, b)
(a, 0)
(b, 0)

Solution :Given EQUATION of parabola is `y^(2) = (a-b) (X-a)`
`RARR Y^(2) =(a-b) X, " where " Y= y & X = x-a "" :."Vertex"=(0,0)`
`rArr X =0, Y=0 rArr x-a =0, y=0 rArr x=a, y =0`
Co-ordinates of vertex are (a,0)
