If f : R R is an even function then
Options
- Af'(0) = 1
- Bf'(x) is an even function
- Cf(0) = 0
- Df'(x) is an odd function
Correct answer
D. f'(x) is an odd function
Step-by-step solution
Given that f(x) is an even function, we have: f(-x) = f(x) Differentiating both sides with respect to x , we get: -f'(-x) = f'(x) f'(-x) = -f'(x) This condition satisfies the definition of an odd function. Therefore, f'(x) is an odd function. Answer: f'(x) is an odd function
