Question:medium
The chord joining the points \( (5,5) \) and \( (11,227) \) on the curve \( y = 3x^2 - 11x - 15 \) is parallel to tangent at a point on the curve. The abscissa of the point is
The chord joining the points \( (5,5) \) and \( (11,227) \) on the curve \( y = 3x^2 - 11x - 15 \) is parallel to tangent at a point on the curve. The abscissa of the point is
Show Hint
Parallel lines have equal slopes — use this to link chord and tangent.
