consider each one in turn (a) - is x necessarily negative?

d?

1 is less than 2
vanessaperezxo
  • vanessaperezxo
ok, x can be anything less than 2... so it can be 1, 0, -1, -2, -3 etc.

@welshfella ,bt we cant say x will be negative as x can be =1 as well
vanessaperezxo
  • vanessaperezxo
So out of all the answers I would have to agree that D is the answer unless there is more to the question
vanessaperezxo
  • vanessaperezxo
Because x could be a negative and it could be a positive so that rules out a and b.
welshfella
  • welshfella
yes definitely not a or b

  • anonymous
yup @vanessaperezxo
vanessaperezxo

The question is telling you that x is less that 2 (x<2) so there is no possible way that the answer is c... because x can NOT be greater than 2
welshfella
  • welshfella
now as for c x can be 1 and 1^2 = 1
vanessaperezxo
  • vanessaperezxo
So, that leaves you with D
welshfella
  • welshfella
but if x = 1.9 x^2 = 3.61

:( ....den what is the ans
welshfella
  • welshfella
none are always true
vanessaperezxo
  • vanessaperezxo
@welshfella but remember the question is telling you that x is less than 2.. so.. c is saying that x is greater than 2
vanessaperezxo
  • vanessaperezxo
tbh d only makes sense because it says anything less than 2... but it also says less than or equal to and the problem doesn't tell you it's equal to it
vanessaperezxo
  • vanessaperezxo
If I could pick 2 I would go with a and b because it could be positive or negative.
welshfella
  • welshfella
no neither of them are always true - that's the key word ALWAYS
welshfella
  • welshfella
are you sure you have the questsion correct @yashiii

yup question is correct @welshfella
vanessaperezxo

And the answers are correct too?
anonymous
  • anonymous
yup dr
vanessaperezxo
  • vanessaperezxo
ohhh wait! I got it!
welshfella
  • welshfella
if we take the answers as they are written then none of them are always true.
vanessaperezxo
  • vanessaperezxo
in this answer you can pick more than one! So the answer is A and B.... Because it is asking which one is ALWAYS TRUE.. A and B are always true... always
vanessaperezxo
  • vanessaperezxo
Because x can be a positive so thats true.. but x can also be a negative, which is also true!
