a) what is the domain of f(x)

b) use a sign table to to find the intervals on which f(x) is positive and where it is negative

c) where is f(x) increasing, and where is it decreasing

d) where is f(x) concave up, and where is it concave down

e) does f(x) have any horizontal or vertical asymptotes? find them

f) draw the graph
