\[f(-1) = \frac{ 12 }{ 4 \times (-1) + 2 } = \frac {12} {-2} = -6\]

The answer is -6

Answer 4

thank u so much!

Answer 5

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!
