Find the number of distinct real tangents that can be drawn from the point (0, -2) to the curve y² = 4x. Classmates scrambled for the formula

The Calculus of Grit

The room was silent. A boy behind him started hyperventilating. Arjun closed his eyes. He saw the grey Cengage cover. He remembered a similar problem from Parabola – Exercise 3, Multiple Correct, Question 17. He recalled the trick: the tangent at (at², 2at) for y²=4ax. Here a=3. t = y/(2a) = -6/(6) = -1. Tangent: y*(-1) = x + 3*(-1)² → -y = x+3 → x+y+3=0. Directrix: x = -3. Intersect P: (-3,0). Focus: (3,0). Distance = 6. He finished it in 45 seconds

One night, after scoring a pathetic 38 in a full syllabus test, his father quietly asked, "Beta, where is the problem?"
