Answer:

A. f^-1(x) = x³ -12

Explanation:

The inverse function can be found by solving ...

x = f(y)

x = ∛(y +12) . . . . . use the definition of f(x)

x³ = y +12 . . . . . . . cube both sides to eliminate the radical

x³ -12 = y . . . . . . . add -12 to isolate the y-variable

f^-1(x) = x³ -12 . . . matches choice A
