7) Use the limit definition of the derivative to show that

8) Consider the function:

Find the open intervals where f is increasing, decreasing, concave up, and con- cave down. Find the x-coordinates of all local minimums, maximums, and in- flection points. Give the equations of any horizontal or vertical asymptotes.
