Question 1128650

Dollars per "ask"?  Come on, please proofread your posts BEFORE you hit send.


Of course "interpret" means something.  It means that you are supposed to describe the meaning of the mathematical model in real life terms.


Consider *[tex \LARGE k(a)\ =\ 0].  Since *[tex \LARGE k(a)\ =\ 0\ \Right a\ =\ -10] but *[tex \LARGE a] is restricted to the non-negative integers, the solution set of *[tex \LARGE k(a)\ =\ 0] is the null set.  That is to say, there is no positive integer *[tex \LARGE a] so that *[tex \LARGE 10a\ +\ 100\ =\ 0].  In real life terms, even if you didn't manufacture ANY "asks" of 100% Organic Guru Energy drink, you would never have a zero expense.


If *[tex \LARGE p(a)\ =\ 0], then in order to have a demand of 35 "asks" you have to set the price at zero.  A ludicrous situation in real life to be sure. I question the wisdom of including the high endpoint on the domain restriction.


I'm guessing that the lesson here is that, in order for some mathematical models to be meaningful, you must restrict the range as well as the domain of the function.

My calculator said it, I believe it, that settles it
