To determine where f is increasing or decreasing, we need to apply the following rules:

The function is increasing when:


\begin{gathered} b>a \\ f(b)>f(a) \end{gathered}

And the function is decreasing when:


\begin{gathered} b>a \\ f(b)Now, let's evaluate the first interval: [tex](-\infty,0)

In this interval f(b) is lower than f(a): f(b)The second interval is (0,4).

In this interval f(b) is greater than f(a), then f
