11Draw the graph of f(x).It will have one root between -2and -1(Say a); 0 and 1(b) and 1 and 2(say c).
Now for F(F(x)), Find roots of f(x)=a, f(x)=b, and f(x)=c.These are the roots of f(f(x)).
Thinking what to do for f(F(F(x)))....
if f(x)=x3-3x+1 then fiind the number solution of f(f(fx)).
plzzz do solve in detail nd explain how to solve..
