Given that f is a real valued differentiable function such that `f(x) f'(x) lt 0` for all real x, it follows that

If f is a real-valued differentiable function such that f(x) f'(x)lt0 for all real x, then

If f is a real- valued differentiable function such that f(x)f'(x) lt 0 for all real x, then

If f is a real-valued differentiable function such that f(x)f'(x)lt0 for all real x, then -

If 'f' is a real valued differentiable function such that f(x) f'(x) < 0 for all real x, then

If f is real-valued differentiable function such that f(x)f'(x)<0 for all real x, then

If f is real-valued differentiable function such that f(x)f'(x)<0 for all real x, then

If f is real-valued differentiable function such that f(x)f'(x)<0 for all real x, then

If f is a real valued differentiable function satisfying | f (x) - f (y) | le (x - y) ^(2) for all real x and y and f (0) =0 then f (1) equals :

f(x) is real valued function such that 2f(x) + 3f(-x) = 15 - 4x for all x in R . Then f(2) =

Let f be a real valued function such that f(x)+3xf(1/x)=2(x+1) for all real x > 0. The value of f(5) is
