Negative function - invert the signs. Inverse function - interchange the $x$ and $y$ variables.

The original function, $f(x) = x^2/(x+2)$ , when introduced a negative, simply results in inverting all the signs.

As a result, you get: $-f(x) = -(x^2)/(x+2)$ .

Please don't get confused with the inverse notation: $f(x)^-1$ . Completely different than the negative function.

Hope this helps :)
