    Here I have graphed y and y'
    y'=0 where x=4.139 (to 3decimal places)

    so there is a local minimum at x=4.139
    If the domain was restricted to (0,\infty] (I think that is how you write it, please correct me if i am wrong)
    then this would be the minimum.

    (0, \infty)

    we don't want to allow zero since there would be a 4/0 term and that's not defined.

    \infty always gets a )
