Answer 1

If you have \(-f(x)\), then the original function, \(f(x)\), will be flipped over the x-axis.

On the other hand, if you had \(f(-x)\), then the original function. \(f(x)\), will be flipped over the y-axis.

Answer 2

In this case, you have \(g(x) = -f(x)\), therefore the function \(f(x)\), is flipped over the x-axis.
