To determine the intervals on which the function is increasing from the graph you provided, I'll analyze the sections of the graph where the function values rise as the $x$-values increase from left to right.

From the graph, the function is increasing in these intervals:

• From approximately $x = -10$ to $x = -8$
• From approximately $x = -3$ to $x = -1$
• From approximately $x = 2$ to $x = 4$
• From approximately $x = 7$ to $x = 10$

Using interval notation:

• $(-10, -8)$
• $(-3, -1)$
• $(2, 4)$
• $(7, 10)$

Would you like any additional details on how these intervals were determined or help with another part of the graph? Here are some additional topics we could explore:

1. How to determine when a function is decreasing.
2. How to identify local maxima and minima from a graph.
3. The concept of concavity and points of inflection.
4. How to sketch a derivative based on the graph of a function.
5. The importance of scale and accuracy in reading graphs.

Tip: When identifying intervals of increase or decrease from a graph, look for the direction of the y-values as x increases; an upward trend indicates increasing intervals.
