" 21."x+(1)/(x)=3,x!=0

if f(x) is a real valued function defined as f(x)={min{|x|,1/x^2,1/x^3},x != 01, x=0 then range of f(x) is

If x=(5-sqrt(21))/(2) then prove that (x^(3)+(1)/(x^(3)))^(2)-5(x^(2)+(1)/(x^(2)))+(x+(1)/(x))=0

Let f(x)={x+1,x>0 and 2-x,x<=0g(x)={x+3,x<1 and x^(2)-2x-2,1<=x<2 and x-5
