KCET2024MathematicsParabola
The equation of parabola whose focus is (6,0) and directrix is x=-6 is
Options
- Ay^2=24 x
- By^2=-24 x
- Cx^2=24 y
- Dx^2=-24 y
Correct answer
A. y^2=24 x
Step-by-step solution
Focus has positive x -coordinate. So, coordinate of focus =(a, 0) (6,0) a=6 ....(i) Hence, equation of parabola is y^2=24 x [ y^2=4 a x . and using Eq. (i) ]
