If `f(x)=||x-2|-1|-3|`, then Number of solutions of `f(x)=3` are

If f(x)=||x-2|-1|-3| , then Number of solutions of f(x)=1/2 are

If f(x)=||x-2|-1|-3| , then Number of solutions of f(x)=2 are

Let f(x)=x^(2)+3x+2 then number of solutions is

If f(x)={0,x<1 and 2x-2,x<=1 then the number of solutions of the equation f(f(f(x)))=x is

Let f:R rarr R be defined by f(x)=In(x+sqrt(x^(2)+1)), then number of solutions of |f^(-1)(x)|=e^(-|x|) is :

If f(x)=|x|-2|-2 for x in[-4,4] then the number of real solutions of f(f(x))=-1 is
