First represents the set of functions such that there exists positive constants and such that . So in order to show that , we need to find out positive constants and such that

Dividing from each parts gives us

Consider the function , given that , by differentiation we can find the minimum value of function to be , also realize that . Hence we can pick and , we have

this shows that .
