If the normal to the curve y=f(x) at the point (3,4) makes and angle ( 3 4 )^ C with positive X -axis, then f^ (3) is equal to

Options

  1. A-1
  2. B1
  3. C4 3
  4. D- 3 4

Correct answer

B. 1

Step-by-step solution

aligned & Slope of normal = -1 f^ (x) & ( 3 4 )= -1 f^ (3) & -1= -1 f^ (3) & f^ (3)=1 aligned
