Chapter 2.3, Problem 31E

During a nine-hour snowstorm, it snows at a rate of 1 inch per hour for the first 2 hours, at a rate of 2 inches per hour for the next 6 hours, and at a rate of 0.5 inch per hour for the final hour. Write and graph a piecewise-defined function that gives the depth of the snow during the snowstorm. How many inches of snow accumulated from the storm?

If a functionfis increasing on (a,b) and decreasing on (b,c) , then what can be said about the local extremum offon (a,c) ?

Why does the horizontal line test tell us whether the graph of a function is one-to-one?

How are the absolute maximum and minimum similar to and different from the local extrema?

What is the difference between the input and the output of a function?

How do we determine the domain of a function defined by an equation?
