Question

Given `f(x)= x^2/(x+2)` how do you find `-f(x)`?

Answer 1

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

Explanation:

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 :)
