3.3E: Rates of Change and Behavior of Graphs (Exercises)
For the following exercises, find the average rate of change of the functions from \(x=1\) to \(x=2\).
24. \(f(x)=4 x-3\)
25. \(f(x)=10 x^{2}+x\)
26. \(f(x)=-\frac{2}{x^{2}}\)
For the following exercises, use the graphs to determine the intervals on which the functions are increasing, decreasing, or constant.
