Consider the polynomial function given by $$f(x) = 2x^3 - 9x^2 + 12x - 2$$. To find the critical points of this function, we must first determine where the derivative $$f'(x)$$ is equal to zero. Calculate the derivative of the function first, and then find the values of $$x$$ for which the derivative is equal to zero. Finally, select the correct critical points from the options below.
