Use the provided information to sketch the graph of . Assume that is continuous on its domain and that all intercepts are included in the table of values.
Domain: All real , except
To sketch the graph of , we need to determine the intervals where it is increasing, decreasing, concave upward, concave downward, and the asymptotes.
Note that if is positive then is increasing, and if is negative then is decreasing.
is positive on . So, is increasing on .
is positive on . so, is increasing on .
