     quotient rule d ( a(x)/b(x)) = (a'(x)b(x) - b'(x)a(x)) / (b(x))^2  

    a(3) =  f(3) =   2

    a'(3) = f'(3) =     5 

    is the bottom x^2 or x^3  

    if x^3 

    b(x)= x^3  

    b'(x) = 3x^2 

         

    using formula 

    g'(x)  = ( 5*x^3 -  2*3x^2) / (x^2)^4  =  (5x^3 -6x^2)/x^4 

    g'(x) = (5x-6)/x^2 

    at x = 3 

    g'(3) =    (5*3 -6) / (9)  = 9/9 =  1

    if it was x^2,  tell us and somewhere will probably 

    show you the steps.

    use g(x) = T / B means g ' = [ T ' B - T B ' ] / B²...do the computations as the picture is too small to read
