Let f(x) be a differentiable function, A(0, ) and B(8, ) be two points on the curve y=f(x) . Given f(0)=2 and f^ (4)= -3 4 . If the chord A B of the curve is parallel to the tangent drawn at the point (4, f (4)) , then =
Options
- A-4
- B-6
- C2
- D8
Correct answer
A. -4
Step-by-step solution
Point A(0, ) is on y=f(x) f(0)= and also given f(0)=2 Therefore =2 . Since slope of chord A B= Slope of tangent on y=f(x) at x=4 - 8-0 =f^ (4) aligned & -2 8 =- 3 4 & =-4 aligned
