According to the table, f(x) = 13 when x = 5 . This means

$f(5)=13\implies f^{-1}(13) = 5$

From the table we also see that f(x)=5 when x=-9 , so

$f(-9)=5\implies f^{-1}(5)=-9$

So we have

$f^{-1}\left(f^{-1}(13)\right) = f^{-1}(5)=-9$

On the other hand, the table shows f(x)=8 when x=-13 , or

$f(-13)=8\implies f^{-1}(8)=-13$

so the given equation is not true.
