Name:

Let f (x) = 10x

x2 + 1 .

1. Find the domain of f . Write your answer using interval notation.

2. Find the x- and y-intercepts of the graph of y = f (x).

3. Is f even, odd, or neither? Explain.

4. Use a graphing utility to graph y = f (x). From the graph, approximate the intervals over which f is increasing and the intervals over which it is decreasing. List the local maximums and minimums, if they exist, and approximate the range of f .
