Instantaneous Rate of Change: Instantaneous rate of change refers to how fast something is changing at any given moment or specific point. It is represented by finding the derivative.
Delta Notation (∆): Delta notation (∆) indicates a difference or change in value between two variables. In terms of average rate of change, it represents the change in y divided by the change in x over an interval.
Linear Function: A linear function is a mathematical equation that represents a straight line. It has a constant rate of change, meaning the average rate of change remains the same throughout.
