    Solve:

    1. 0 = x^3-3x^2+3

    2. \frac{dy}{dx} = 0.

    3. \frac{d^2y}{dx^2} = 0.

    4. Revise the definitions of the various types of asymptotes.

    Well I know Y=3 Im just not sure how to get the X values when y=o.

    You will struggle to solve this cubic equation exactly using algebraic methods. You're probably expected to get decimal approximations using technology.
