Let y = f(x)

Let cr = cube root for short

y = cr{3x} + 2

Switch x and y.

x = cr{3y} + 2

Solve for y.

x - 2 = cr{3y}

Raise both sides to the 3rd power.

(x - 2)^3 = [cr{3y}]^3

(x - 2)^3 = 3y

[(x - 2)^3]/3 = y

Replace y with the inverse function notation

f^(-1) x.

f^(-1) x = [(x - 2)^3]/3

Choice b is the answer.
