You tell me why the first one is NOT the answer.

tkhunny
  • tkhunny
Because what is less than -5? -6 < -5 and -7 < -5 etc. Okay, now tell me why the last one is NOT the answer.

because they're not all positive numbers ?
tkhunny
  • tkhunny
?? No, it includes -6, doesn't it? We already established that -6 < -5. Okay, how about the number 9. Is 9 > -5?
anonymous
  • anonymous
yes
tkhunny
  • tkhunny
Does the third set contain 9?
anonymous
  • anonymous
yes ?..
tkhunny
  • tkhunny
Try again. The third set is finite and contains no integer greater than 5.
anonymous
  • anonymous
i think the answer is {−5, −4, −3, …} or the last one...
tkhunny
  • tkhunny
We certainly ruled out the other three! Good work.
anonymous

so it is {−5, −4, −3, …} !!!
tkhunny
  • tkhunny
Hold on. I didn't see the fourth one correctly. It does NOT contain -6. It is only POSITIVE numbers. It's problem is two-fold. 1) It contains non-integers, like 3/2 and \(\sqrt{2}\) 2) It fails to contains -3, whcih clearly is greater than -5.

so what does that mean.... ?
tkhunny
  • tkhunny
Nothing new. We ruled it out incorretly, before, but we just ruled it out correctly, so it's still gone and #2 is still the right one. Sorry for confusion.
