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 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)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) < 0 for all real x, then

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 satisfying |f(x)-f(y)|<=(x-y)^(2),x,y in R and f(0)=0 ,then f(1) equals:

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

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