    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

    "I have" would imply "I did this in the past." However, it's in the present since it recently occurred.

    If it occurred that long ago, then you wouldn't say "I have bought" - this indicates something as new as a week ago.

    This is a different case. "I have been to France" is like saying "I did this before."

    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)????

    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.

    "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.

    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.

    To be honest I'm not entirely sure, simply because they're giving me equations as definitions.
