WebFind the maximum value of f(x) = x^3 - 6x^2 + 11x - 6 on the interval [0, 3]. Solution: We can find the critical points of the function by finding its derivative and setting it equal to zero: f'(x) = 3x^2 - 12x + 11 = 0. Solving this equation for x, we find that x = 1 and x = 11/3 are the critical points.
