To find the inverse of the function \( f(x) = 4x + 6 \), we follow these steps:

### Step 1: Set \( f(x) = y \)
\[
y = 4x + 6
\]

### Step 2: Solve for \( x \) in terms of \( y \)
- Subtract 6 from both sides:
\[
y - 6 = 4x
\]
- Divide both sides by 4:
\[
x = \frac{y - 6}{4}
\]

### Step 3: Swap \( x \) and \( y \) to get the inverse function
\[
f^{-1}(x) = \frac{x - 6}{4}
\]

### Step 4: Simplify
This can be rewritten as:
\[
f^{-1}(x) = \frac{x}{4} - \frac{6}{4} = \frac{x}{4} - \frac{3}{2}
\]

Thus, the correct inverse function is:
\[
f^{-1}(x) = \frac{x}{4} - \frac{3}{2}
\]

This corresponds to the second option in the given choices.
