Question
If f : R → R is continuous and differentiable function such that f(t) dt + f¢¢¢ (3) t3
dt – f ¢ (1) t2 dt + f ¢¢ (2) t. dt, then the value of f ¢ (4) is :
- 48 – 8 f ¢ (1) + f ¢¢ (2)
- 48 – 8 f ¢ (1) – f ¢¢ (2)
- 48 + 8 f ¢ (1) + f ¢¢ (2)
- None of these.
The correct answer is: 48 – 8 f ¢ (1) – f ¢¢ (2)
