Answer 2

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. :)

Answer 3

so what is the problem?

Answer 4

its the document I have attached. I don't know another way to put the problem on here other than that

Answer 5

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

Answer 6

the limit, I knew the answer to that one I just don't know how to work it out

Answer 7

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

Answer 8

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

Answer 9

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.

Answer 10

Thank you so much!! Can you please help me with 2 more.

Answer 11

yea, sure I got time.

Answer 12

1.lim x ->4 1/x-3 2.lim x ->0 sin x^2/x

Answer 13

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

Answer 14

1/(x-3)

Answer 15

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

Answer 16

the answer is 1

Answer 17

and I somehow got zero for the second one.

Answer 18

hm.... wait for a sec

Answer 19

i got 2. Did you use l'hospital's rule?

Answer 20

l'hopital*

Answer 21

ok im lost what is that

Answer 22

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.
