    Revenue question

    The total revenue R from the sale of a popular new board game is R=140x^2/x^2+2 where x is the number of years since the game has been released and the revenue R is in millions of dollars.

    a) find the revenue generated by the end of the second year
    b) find the revenue generated by the end of the third year
    c) find the maximum revenue that can be expected as the year increase.

    As we're dealing with time let x=t

    R(t) = \frac{140t^2}{t^2+2}

    a) Find R(2)
    b) Find R(3)

    c) Find R'(t) = 0

    ok this is what i did R(2)=140(2)^2/2^2+2 = 560/6= 93.355555

    R(3)=140(3)^2/3^2+2 = 1260/11= 114.545454

    did i do that right???? and how do i find c???
