allery∫ from -a to a (odd function) dx =
Af(a) - f(-a)
B0 (odd function symmetric about origin)
C2 × ∫ from 0 to a
D∞
Answer & Solution
Correct answer: B. 0 (odd function symmetric about origin)
For odd function (f(-x) = -f(x)): ∫_(-a)^a f(x) dx = 0. (Negative half cancels positive half.) For even functions (f(-x) = f(x)): ∫_(-a)^a = 2 × ∫_0^a.
