Ups and Downs. Consider the function $f(x) = x^3-3x^2+2x.$ This function is increasing on the interval $(-\infty,A)$ where $A$=
It has an inflection point at $x=$ Call that point $B$. For each of the following intervals, tell whether $f(x)$ is concave up (type in CU) or concave down (type in CD).
$(-\infty, B)$:
$(B,\infty)$:
