Chapter 2, Problem 22RE

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?

How can you determine whether a function is odd or even from the formula of the function?

Assume that all variables represent real numbers. Determine whether each equation determines y to be a function of x. x=|y|
