To find the inverse of the function \( f(x) = x^3 + 3 \) algebraically, follow these steps:

1. Start with the function: 
   \[
   f(x) = x^3 + 3
   \]
   We aim to find \( f^{-1}(x) \), the inverse function.

2. To do this, first replace \( f(x) \) with \( y \):
   \[
   y = x^3 + 3
   \]

3. Swap \( x \) and \( y \) to reflect that we are now solving for the inverse:
   \[
   x = y^3 + 3
   \]

4. Solve for \( y \):
   \[
   x - 3 = y^3
   \]

   Now, take the cube root of both sides:
   \[
   y = \sqrt[3]{x - 3}
   \]

5. Thus, the inverse function is:
   \[
   f^{-1}(x) = \sqrt[3]{x - 3}
   \]

So, the inverse function of \( f(x) = x^3 + 3 \) is:
\[
f^{-1}(x) = \sqrt[3]{x - 3}
\]

When finding the inverse of a function, always ensure the original function is one-to-one (bijective), as this guarantees the existence of an inverse function.
