Answer:
A
Step-by-step explanation:
f(x) =³√(x+12)
Let, y=³√(x+12)
Exchanging x and y,
x=³√(y+12)
Cubing on both sides,
x³=y+12
x³-12=y
f-¹(x) =x³-12

Hi there! Her mistake is in step 1.
She subtracted -25 by 25. -25 - 25 = -50
What she SHOULD have done was add 25 to each side. This obeys the property of reciprocals.
-25 + 25 = 0
Hope this helps.
:)
