Question

# If f : R → R is continuous and differentiable function such that f(t) dt + f¢¢¢ (3) t^{3}

dt – f ¢ (1) t^{2} 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)
