The graph of the function \$f\$ is shown below. How many solutions does the equation \$f(f(x)) = 6\$ have?

Let's see...

f(1)=6    and f (-2)=6

so when is   f(x)=1     or   f(x))=-2

f(x)=1      4 times             [ because the line graph crosses the line y=1  four times. ]

f(x)=-2     2 times

So there are 6 answers to     f(f(x)=6
