Show that maximum or minimum of f(x) is a minimum or maximum of `1/f(x)`, where f(x) and 1/f(x) are well defined.

Show that the maximum value of f(x)=x+(1)/(x) is less than its minimum value.

Let f(x)= Maximum {sin x,cos x}AA x in R minimum value of f(x) is

How to find out minimum and maximum values of x and f(x) if f(x)=ax^(2)+bx+c

Find the maximum and minimum values of f(x)=(1-x)+|x|

Find the maximum and minimum value of f if any of the function f(x)=|x-1|, x in R .

If a function f(x) has f'(a)=0 and f''(a)=0, then x=a is a maximum for f(x)x=a is a minimum for f(x) it is difficult to say (a) and (b)f(x) is necessarily a constant function.
