Find the equation of the parabola in each of the case given below :
(i) Focus ( 4,0) and direction x = -4.
(ii) passes through ( 2,-3) and symmetric about y-axis.
(iii) vertex ( 1,-2) and forus ( 4,-2)
(iv) end points of latus rectun ( 4,-8) and ( 4,8)

Answer

(i) ` y^(2) = 16 x `
(ii) ` 3x^(2) = -4y`
(iii) ` (y+2)^(2) = 12 (x-1)`
(iv) ` y^(2) = 16x`
