Understanding Rate of Change Concepts

This video from the '2-minute math' series explains the concept of rate of change, emphasizing its importance and practicality in everyday life. It introduces the mathematical definition of rate of change as the slope, or rise over run, and uses the Greek letter Delta to represent change. A practical example involving Snapchat is provided, where the rate of change is calculated based on the number of snaps sent per day. The video concludes with a call to action for viewers to engage with the content by liking, subscribing, and hitting the notification bell.
