$$f(-1) = \frac{ 12 }{ 4 \times (-1) + 2 } = \frac {12} {-2} = -6$$

The answer is -6

I thought you were doing inverses!  No wonder I couldn't get the answer!  You also denote the inverse of a function with f(-1), but usually the (-1) is in the exponent position.  This is much easier than I was making it!
