" 44.Range of "f(x)=(2008^(x)+2008^(-x))/(2)" is "

Range of f(x) = (x+2)/(|x+2|)

Range of f(x)= (x^(2)-x)/(x^(2)+ 2x) is …….

Range of f(x) = |x-2| is

Range of f(x) = |x-2| is

Let f(x)=((2008)^(x)+(2008)^(-x))/(2),g(x)=((2008)^(x)-(2008)^(-x))/(2) then prove that f(x+y)=f(x)f(y)+g(x)g(y)

The range of f(x)=x^(2)+x+1 is

The range of f(x)=(x)/(1+x^(2))

The number of integers for which the function f(x)=^(2008)C_(2x-1000)+^(200-x)C_(3x) is defined is

(-1)^(2008)=-1 .
