If vertex is at (1, 2) and focus (2, 0) then find the equation of the parabola.(a) y^2-8x+4y+12=0(b) y^2-8x-4y-12=0(c) y^2-8x-4y+12=0(d) y^2+8x+4y+12=0The question was asked in final exam.My enquiry is from Conic Sections in chapter Conic Sections of Mathematics – Class 11

Answer»

The CORRECT option is (C) y^2-8x-4y+12=0

Easiest EXPLANATION: Since vertex is at (1, 2) and FOCUS (2, 0) so parabola equation will be

(y-2)^2=4*2(x-1)

y^2-8x-4y+12=0.
