    Marginal and Average cost functions

    I cant seem to figure these out.
    Find the marginal average cost function if the cost function is given by

    C(x)= .04x^2 + 30x + 500

    Then :

    Find the absolute minimum of this average cost function
    C(x) = .01x^2 + 10x + 400 all divided by x

    C(x) is the cost for producing x units, therefore, the cost for producing 1 unit is given by C(x)/x
    And the marginal for average cost is just the derivative of C(x)/x
