1. Explain in your own words what it means for a function to be increasing on an interval. How does this relate to the slope of the function's graph on that interval?
2. Sketch a graph of a function that is increasing from x = -3 to x = 1, decreasing from x = 1 to x = 5, and then increasing again from x = 5 to x = 8.
3. Consider a function f(x). If f'(x) > 0 on the interval (a, b), what does this indicate about the behavior of f(x) on that interval?
