    First of all, U've to get \[f^{-1}(x)\] To get it from \[f(x)\] you have to get all of the x's in the original function in one hand and the rest of the original function on the other hand (y) For your case : \[f^{-1}(x) = 3x + 5\] Then you will subs. by desired value to get the answer which will be 14 Let me know if you got it :)
