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
