Have 20 Calc problems, and stuck on 5, only have 2 tries left to submit them or I loose credit so getting nervous! Thanks for your help!
Let

4)Use interval notation to indicate the domain of f(x)= (11-6x)^(1/2) Note:read as square root of (11-6x).
Note: When entering interval notation in WeBWorK, use I for , -I for , and U for the union symbol. If the set is empty, enter "{}" without the quotation marks.
Domain =

7)Given the logarithmic function : y=logax note(that should be log sub a times x)
(a) What is the domain of the function?
(b) What is the range of this function?

Please enter an interval below, including appropriate parentheses and commas.

(a)
(b)

11)Put the function P=15(3.2)^(t) in the form P0e^(kt) Note this one is read as P sub zero times e^kt. When written in this form, you have:
k=
P0+

I think this counts as cheating. If you don't know the answers, why do you deserve the credit?

Scrappychimow

Yeah , this is TCD. How did you get into TCD? how fcuking dare you walk through the front arch.

Don't bother respondin to something if you don't approve, surely it's a waste of time where your inestimable mind could be bettering the world!

OP, I can barely add but I know that lecturers have been known to lurk on Boards and your username is not exactly a masterpiece of disguise. Just a friendly word of advice.

Don't get too worried about these 1E1 questions. You have lots of them throughout the year, so each question is worth a minuscule amount of the overall subject result.

Have a look through the book, it is explained quite well, and has some good examples too.

Good luck

If you bring your questions to the Maths Helproom someone will give you a hand.
