If three normals can be drawn from (h,2) to the parabola y2=−4x, then _____?
- h is any real number
- h<−2
- h>2
- 2<h<2
Explanation
For the parabola y^2 = −4x, three normals can be drawn from a point (h, 2) to the parabola only if h < −2.
This condition ensures that the point lies in the correct region where three normals are possible.
