Question

Use the graph below to determine the intervals on which:

Answer 1

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:

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
