1. Defina \( y \):

y = x^5 - 2

2. Troque \( x \) e \( y \) e resolva para \( y \):

x = y^5 - 2

3. Adicione 2 a ambos os lados para isolar \( y^5 \):

x + 2 = y^5

4. Tire a raiz quinta de ambos os lados para resolver \( y \):

y = \sqrt[5]{x + 2}

5. Portanto, a função inversa é:

f^{-1}(x) = \sqrt[5]{x + 2}
