if f(x)=(3x-27)/14 then find f(f^-1(241))

f(x) = (3x - 27)/14

f(f^-1(241))

the inverse of our function f^-1(241) = 14/(3x - 27)

= 14/(3*241-27) = 0.0201

then f(f^-1(241)) = f(0.0201) = (3(0.0201) - 27)/14 = -1.92

actually the correct answer is 241 itself because it must start and end the same
