Questions: Determine all intervals on which the graph of f is increasing.

Transcript text: Determine all intervals on which the graph of $f$ is increasing.

Solution

Step 1: Identify the intervals where the graph is increasing

To determine where the graph of $ f $ is increasing, we need to look for sections where the graph is moving upwards as we move from left to right.

Step 2: Analyze the graph

From the graph, we can see that the function $ f $ is increasing in the following intervals:

Step 3: Write the intervals in interval notation

The intervals where the graph of $ f $ is increasing are:

The graph of $ f $ is increasing on the intervals $ (-7, -4) $, $ (1, 4) $, and $ (6, 8) $.
