Understanding Average Rate of Change

The video tutorial explains how to find the average rate of change for the function f(x) = 3x^2 - x over a closed interval from 2 to T. It begins by introducing the concept and relates it to finding the slope between two points. The tutorial then demonstrates the calculation of f(2) and f(T), followed by determining the average rate of change using these values. The process involves simplifying the expression and factoring, leading to the formula 3T + 5. An example is provided to illustrate the application of this formula for a specific interval.

What is the average rate of change of a function equivalent to?

• The slope of a tangent line

• The slope between two points
