Find an example of the function such that the limit exists at every x, but has an infinite number of discontiniuities. (You can explain through graph, formula or a function).

The graph of fx=1/x is a .

If a function f is an even function, then what type of symmetry does the graph of f have?

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?
