Best answer 1 votes 1 votes Given that $f(x)=3x-6\implies y = 3x-6$ $f$ and $f^{-1}$ cancels each other and so $f(f(f^{-1}(3)))= f(3) = 3\times 3 - 6 = 3.$ gatecse answered Jul 12, 2020 • selected Jul 10, 2021 by Arjun gatecse comment Share Follow See all 0 reply Please log in or register to add a comment.
