In an inverse variation, the values of the two variables change in an opposite manner  as one value increases, the other decreases.

Well, it says that inverse variation involves two quantities wherein as the other one increases, the other decreases. Take for example: 8 workers paint a house for 5 days; 10 workers paint the house for 2 days. Since there are more workers, the work could be done in a shorter time. That's inverse variation. Do you somehow get it?

so what do you think ??? does f(x) increase or decrease with x??

experimentX Group TitleBest ResponseYou've already chosen the best response.2
f(1) = 1/1 = 1 f(10) = 1/10 = 0.1 do you think it is increasing

imagreencat Group TitleBest ResponseYou've already chosen the best response.1
Well, with the denominator increasing, what do you think will happen to the quotient of 1 and the increasing denominator?
 2 years ago

imagreencat Group TitleBest ResponseYou've already chosen the best response.1
Just think of it this way, the number 1 is divided into greater and greater parts. So great that it will reach infinity! Do you now think it is still increasing?

Yes, well A is correct. Go check the other ones. Tell us what you think of each option.

experimentX Group TitleBest ResponseYou've already chosen the best response.2
since it's inverse variation ... it cannot be direct variation now two option left

The range can't be zero. So the range is not all real numbers.

i'm still not sure if you can consider infinity to be real numbers or not generally ... i have said lim x>inf 1/x = 0
 2 years ago

imagreencat Group TitleBest ResponseYou've already chosen the best response.1
Well yeah. But as far as I can remember, my calc teacher told me that infinity is not a number. That's why you can't close bracket the infinity sign. :)

experimentX Group TitleBest ResponseYou've already chosen the best response.2
I guess you are right http://en.wikipedia.org/wiki/Extended_real_number_line there's been a long debate on infinity ... observing it only made me confused still ... lim x> inf ... will never make 0 on range

well ... A and D are your answer

Yup! =)) Cause that is just the limit and we are not actually sure if it will be 0.
