Write your questions and thoughts here! Average Rate of Change Average rate of change measures how much the function changed, on average, over a given interval. You can think of the average rate of change as the slope of a line joining two points on the function. The average rate of change describes how an output quantity changes relative to the change in the input quantity. To find the average rate of change of a function, f , on the interval [ x 1 ,x 2 ] , we use Example: If we look at the following graph, we can see that the graph does not always increase at the same rate. 1) What is the average rate of change of the function on the interval [0, 2]? 2) What is the average rate of change of the
