    Hi I am sorry but I am not very good at math and don't know how to help you with this problem. The way that it is presented is kind of confusing to be honest. But I wish you the best of luck with it, have a good rest of your day. :)

    Well, the limit is 45, so are you asking for the limit or are you asking for something else?

    ahh, just plug 3 into x and you get your limit.

    limits are like substitutions in some ways. However, some limits are a bit more special.

    for example 1/x-5 when x approaches 5. If it approached from the right side, it will go to infinite, if it approached from the left side, it will go to negative infinite.

    for the first question, is it 1/(x-3) or is it (1/x)-3

    ok, plug in x=4, and your limit should come out.

    basically, when the limit (the number you plug in) will result in 0/0 or infinite/infinite, the equation would equate to the derivative of the top and bottom. I'll get you a vid to show you how it works.
