1. the graph of f has a point of inflection at (0,-2).

2. The average value of f(x) on the closed interval (0,-2) is -3.

Determine the values of a,b and c

f'' = 6x + 2a

f''(0) = -2, so

6*0 + 2a = -2

a = -1

f = x^3 - x^2 + bx + c

Hey! (0,-2) is

a) not a closed interval

b) not written as [low,hi]

Watch this space for further correct info.
