Faktormengenkobination + Definitionsbereiche

Hello Melody,

Thank you for your note.
The question was:
 In which area is the economically meaningful definition area?
Perhaps the x before the equals sign should be a y.
That would have interested me.

Die Frage war:
In welchem Bereich liegt der ökonomisch sinnvolle Definitionsbereich?
Vielleicht sollte das x vor dem Gleichheitszeichen ein y sein.
Das hätte mich interessiert.

asinus :- ) !

Thanks asinus, yes I expect that was the question but I am not into guessing questions too much.

If the student does not understand enough to know that there must be a y in the question then they will not understand any of our answers anyway.  And if it is a typo the student needs to learn to be more careful.

Would you like me to talk about

$y=\frac{3}{x-2}+1$

Here is the graph:

I'd say it is only sensible for the domain (2, infinty)  

The range is y>1     or   (1,infinity)

I do not really know if this is reslevant to your question but the area under the curve from x=2 to infinity is infinite.

$\displaystyle\int_2^\infty\;\;\frac{3}{x-2}+1\;dx\;=[3ln(x-2)+x]_2^\infty\; = \infty$I did the integral but my internet went down and I've lost it.  It is not terribly relevant anyway since the area is infinite.

I do not know about the rest of the question, sorry :(

The integral reappeared - how very strange.  Web2.0 really does have its own ghost. :)

Das Integral erschien wieder - wie seltsam. Web2.0 hat wirklich seinen eigenen Geist. Aufrechtzuerhalten.  :)

You're right in everything, Melody.
Thanks and have a nice evening,
wherever you are at home!
