a) Find all points in the interval [-1, 2] where the function f(x) = x^3 - x^2 satisfies
the conclusion of the Mean Value Theorem.
I don't get it...i get to the point where i get 3x^2 - 2x = 2 , then i don't know how to get x
b) f(x) = ln(x + 1) with domain [0; 3].
i got abs maximum as f(3) = ln4 and abs minimum as f(0)=ln1 ..lemme know if that is correct.
Prove that the function f(x) = x^3 + 7 + 4= x^2 has at most one zero in the interval
