Suppose f is defined by f(x)=3x/(4+x^2), −1≤x<3.

What is the domain of f?

Find the intervals where f is positive and where f is negative.

Does f have any horizontal or vertical asymptotes. If so, find them, and show your supporting calculations. If not, briefly explain why not.

Compute f′ and use it to determine the intervals where f is increasing and the intervals where f is decreasing.

Find the coordinates of the local extrema of f

Make a rough sketch of the graph of f using only the information from the previous steps.
