no
sparrow2

they exist and i can help you if you help me with my english
sparrow2
  • sparrow2
beneficial for both
anonymous
  • anonymous
Err.. Sure? Dunno what you'd need to know, but I guess I can help.
sparrow2
  • sparrow2
i need help with tense and article
sparrow2
  • sparrow2
okay i trust you on word,
sparrow2
  • sparrow2
so lim x goes to 2(from left ) mean that x is approaching 2 from lef(there is minus)
sparrow2
  • sparrow2
u here?
anonymous
  • anonymous
Still here, go ahead.

sparrow2
  • sparrow2
so they ask you,when this happens (x is very close to 2 from left..1.99 1.999, 1.999 ...) then f(x) approaching what number? in your case f(x) is 3
sparrow2
  • sparrow2
it doesn't matter in this point so in x=2 function is defined or not.
anonymous
  • anonymous
So the solid lines would be f(x)?
sparrow2
  • sparrow2
yes it function f(x)
sparrow2
  • sparrow2
so it will be 3:-3 your answer
anonymous

Alright, I see.. I may have another one for you if you're up to it. And of course any questions you have regarding your English lessons can be posted here (since tagging notifications aren't working for me in other topics)
sparrow2
  • sparrow2
okay just i'm confused with present perfect. why it is present if it describes action in the past.what is difference betwenn present perfect and past simple?i know that when time is defined you use past simple but still confused
anonymous
  • anonymous
You'll have to give me an example sentence so I can explain it.
sparrow2
  • sparrow2
okay i have bought a car and i bought a car two days ago
sparrow2
  • sparrow2
why it is called present?
triciaal
  • triciaal
you just did it, happen now. now is present
anonymous
  • anonymous
"I have" would imply "I did this in the past." However, it's in the present since it recently occurred.
sparrow2
  • sparrow2
mayby it happened like 30 years ago
sparrow2
  • sparrow2
is it still recently?
triciaal
  • triciaal
basically answer the question when the action was done
anonymous
  • anonymous
If it occurred that long ago, then you wouldn't say "I have bought" - this indicates something as new as a week ago.
sparrow2
  • sparrow2
i'm confused. for ex: i have been in france.. (mayby i was 30 years ago or smth,why i cant' use present perfect here? )
sparrow2
  • sparrow2
it occured that long
anonymous
  • anonymous
This is a different case. "I have been to France" is like saying "I did this before."
sparrow2
  • sparrow2
so i need generall concept no for specific.
sparrow2
  • sparrow2
so in present perfect you emphasize that for now i have done this thing(i don't focus on when it happend or under what circumstances..just point out that you have done that thing)????
sparrow2
  • sparrow2
but i don't get when people say: you use present perfect when time is unfinished? what means unfinished time?
anonymous
  • anonymous
There are different cases when you're trying to explain something. Usually people don't say "I have been," they abbreviate it with "I've been to France" just to show that they've gone there before. "Unfinished time" is usually something continuous, like the graph in the question.
sparrow2
  • sparrow2
and why it is used with present perfect?
sparrow2
  • sparrow2
time when you did this action is certainly finished
anonymous
  • anonymous
You'll have to gimme another example on that one.
sparrow2
  • sparrow2
just tell me why they connect "unfinished time" and "present perfect" if this connectin exist of course
anonymous
  • anonymous
"I have worked at the plant" explains that you've done this before, or you currently work at a power plant and do this on a daily basis. Although a lose explanation, it still serves its purpose. "I have *just* bought a car" explains that you've done this recently, within a week or so. "I have bought a car" suggests you've done this in the past, with no real set time.
anonymous
  • anonymous
If that helps.
sparrow2
  • sparrow2
okay. if i say that " i have lived here for 2 years.. does it mean that i'm still living here?
anonymous
  • anonymous
That just means you have done this, but the sentence is unclear on if you still do. Since you're saying "here," it would imply that you do.
sparrow2
  • sparrow2
okay if i say: i have lived in england for 2 years ..i understand that this means that i have done this(mayby when i was little,but it doesn't mean that i'm still living here) or so?
anonymous
  • anonymous
Correct.
sparrow2
  • sparrow2
okay thanks very much .. just tell me your next question
sparrow2
  • sparrow2
but i'm little bit busy and mayby i can't reply right away
anonymous
  • anonymous
Here you go. http://i.imgur.com/tzeZ8NW.png
sparrow2
  • sparrow2
it's -3
sparrow2
  • sparrow2
so just tell me what you don't get
anonymous
  • anonymous
I had thought that, but you'll have to explain WHY it's -3.
sparrow2
  • sparrow2
do you know the meaning of limits?what is it or so?
anonymous
  • anonymous
To be honest I'm not entirely sure, simply because they're giving me equations as definitions.
