Consider the function f(x)=12x^5+75x^4 -120x^3+1. (It is 12x^5 + 75x^4 -120x^3 + 2).
f(x) has inflection points at (reading from left to right) x=D, E, and F
Where D is _______
Where E is_______
Where F is________
For each of the following intervals, tell whether f(x) is concave up (type in CU) or concave down (type in CD).
(negative infinity,D]: ______
