For the function \( f(x) = \frac{1}{4}x - 2 \), let's find the inverse step by step.

### Steps to Find the Inverse:

1. **Rewrite the function with \( y \):**

   \[
   y = \frac{1}{4}x - 2
   \]

2. **Swap \( x \) and \( y \):**

   \[
   x = \frac{1}{4}y - 2
   \]

3. **Solve for \( y \):**

   - Start by isolating the term with \( y \):

     \[
     x + 2 = \frac{1}{4}y
     \]

   - Multiply both sides by 4:

     \[
     4(x + 2) = y
     \]

   - Simplify:

     \[
     y = 4x + 8
     \]

### The inverse function is:

\[
f^{-1}(x) = 4x + 8
\]
