The entire graph of the function \(f(x)\)  is shown below (  \(f\) is only defined when \(x\)  is between \(-4\)  and \(-5\)  inclusive). How many values of x satisfy f(f(x)) = 2 ?

f(f(x))  = 2   when  f(x)   = -3 , 0   and 3

 

When f(x) = -3.....the value of x is not defined

 

When f(x)  = 0, x = -4

 

When f(x)  = 3, x = -2 and 4

 

So....the solutions are x= -4, x = -2  and x = 4

 

 

cool cool cool
