    Nevermind XD you're making the error of plugging zero directly in for x. You need the right hand limit. That's going to be negative infinity (ln x as x approaches zero becomes negatively large and dividing that by an infinitely small number makes that number even larger and more negative)

    if i plug in a small number to the right of X, should ln(x) equal a small number.. and dividing by a small number would give me a larger number/

    ln(x) should equal a large number that is also negative (you can check this by plugging in ln (.0000001) into your calculator
