Να σχεδιαστεί το γράφημα της συνάρτησης g(x) = x^3 - 4x^2 + 2x.
The graph of the function g(x) will be a straight line.
The graph of the function g(x) will have a local maximum at x = 2.
The graph of the function g(x) will have no critical points.
The graph of the function g(x) = x^3 - 4x^2 + 2x will have a local minimum at x = 2 and will be concave up to the left of x = 2 and concave down to the right of x = 2.
