problem

Suppose that

f

is a function and

f^{-1}

is the inverse of

f

. If

f(1)=2

f(2) = 6

, and

f(3)=5

, then what is

f^{-1}(f^{-1}(6))

Plain-text mathematical notation (without MathML)

Suppose that f is a function and f^(−1) is the inverse of f.  If f(1)=2, f(2)=6, and f(3)=5, then what is f^(−1)(f^(−1)(6))?

Original LaTeX notation

Suppose that $f$ is a function and $f^{-1}$ is the inverse of $f$.  If $f(1)=2$, $f(2) = 6$, and $f(3)=5$, then what is $f^{-1}(f^{-1}(6))$?
