What is the average rate of change function for the function ?
Find the average rate of change of when varies from 1.3 to 2.
For a function , the rate of change at a fixed is . Given that , find when .
Consider the average rate of change of the function over the interval with small values of .
Simplify the expression .
The average rate of change gets closer and closer to as becomes smaller and smaller. Simplify the expression for the difference between and .
For what values of is the difference exactly , , . Give your answer as a fraction.
