This is the problem:
Let f be a function defined by f(x)= x3+ax2+bx+c and having the following properties:
I) The graph of f has a point of inflection at (0, -2).
II) The average (mean) value of f(x) on the closed interval [0,2] is -3
a) What are the values of a,b, and c?
b) Determine the value of x that satisfies the conclusion of the Mean Value Theorem for f on the closed interval [0,3]
I got that a=0 by calculating the second derivative, and then plugging in the inflection point. But I would really appreciate some help with the rest of the problem. Thanks to anyone who can help me out!!
