Question

The number of distinct real tangents that can be drawn from $(0,-2)$ to the parabola $y^2=4x$ is

• A. one
• B. two
• C. zero
• D. none of these

Answer 1

Answer: (B)

two

$S=y^2-4x$
On putting $(0,-2)$ in $S$ we get $S=4>0$
That means the point is outside the parabola hence two tangents can be drawn.
Option B
