Find a formula for the inverse of the function.

Question

f(n)=4en3.

f^[−1](Q)=

Answer 1

Is that

f(n) = 4e^(n^3) ?
n^3 = ln(f/4)
n = ∛ln(f/4)

so, f^-1(Q) = ∛ln(Q/4)

That is kind of strange, so maybe you can fix it and follow the same logic to find the inverse you want.

If you get stuck, show some work...
