f is a strictly decreasing function with range [a, b], its domain is

In case of strictly decreasing function, the derivative is

If the function f(x) = 2cotx+(2a+1) ln|cosec x| + (2-a)x is strictly decreasing in (0, pi/2) then range of a is

If the function f(x) = 2cotx+(2a+1) ln|cosec x| + (2-a)x is strictly decreasing in (0, pi/2) then range of a is

If the function f(x)=2cot x+(2a+1)ln|cos ecx|+(2-a)x is strictly decreasing in (0,(pi)/(2)) then range of a is

Strictly increasing functions and strictly decreasing functions

Define the strictly increasing function and strictly decreasing function on an interval.

The function f(x)=ax+b is strictly decreasing for all x epsilon R if

Show that f(x) = e^(-x) is a strictly decreasing function on Rgt

The function f(x)=ax+b , is strictly decreasing for all x in R iff :

The function f(x)=(x)/(1+|x|) is (a) strictly increasing (b) strictly decreasing (c) neither increasing nor decreasing (d) none of these
