If f(x) is an odd differentiable function defined on ($$-$$$$\infty $$, $$\infty $$) such that f'(3) = 2, then f'($$-$$3) is equal to

$$\int {{{\log \sqrt x } \over {3x}}} dx$$ is equal to

The equation x³ $$-$$ yx² + x $$-$$ y = 0 represents

The number of points at which the function f(x) = max {a $$-$$ x, a + x, b}, $$-$$ $$\infty $$ < x < $$\infty $$, 0 < a < b cannot be differentiable, is
