{\bf 1.} (6 pts) Suppose the function $f$ satisfies $f'(x)=4(x+1)^2(x-2)$. 

(1) Find the critical point(s) of $f$. 

(2) Find the intervals on which $f$ is increasing or decreasing. \\[8cm]

{\bf 2.} (7 pts) Suppose the function $f$ satisfies  $f''(x)=12(x^2-1)$. 

(1) Find the intervals on which $f$ is concave up or concave down. 

(2) Find the inflection point(s) of $f$.  \\[8cm]


{\bf 3.} (7 pts) The function 
$f(x)={x^4}-{6x^2}-8x$ 
satisfies the equations in Problems 1 and 2 above. Use your answers to Problems 1 and 2 to sketch the graph of $f$ (on the back side). Label the critical point(s) and the inflection point(s).
