    You should practice your graph-sketching skills then, simple ones like these shouldn't be taking "too long", once you have some intuition and understanding down, then you can stop drawing graphs everytime you have one of these questions, for now - draw the graphs, seriously.
    ah ok

    \dfrac{1}{x+1}

    and

    \dfrac{1}{x} +1

    The obvious one, they're two different expressions. It's like asking what's the difference between \frac{1}{1 +1} = \frac{1}{2} and \frac{1}{1} + 1 = 2, they're two different numbers.

    The graph of y=1/x clearly.

    Yes, but it's important that you always mention what graph you're transforming.
