Why we use interval notation?

The video tutorial explains how to represent driving a car on a graph, focusing on speed over time. It covers the concept of acceleration and maintaining speed using cruise control. The instructor emphasizes understanding intervals of increasing speed and clarifies the language used to describe these intervals. The tutorial also highlights the importance of focusing on X values when discussing graph intervals, rather than the Y values, which represent the magnitude of change.

What does the graph represent in the context of driving?

What is the significance of cruise control in the context of the graph?

During which time interval were you increasing your speed?

Why is it important to distinguish between when speed is increasing and how much speed is increasing?

Explain the difference between discussing X values and Y values in the context of a graph.
