If n is not equal to 0 which of the following must be greater than n?

Question

1) 2n
2) n (squared)
3) 2-n

I do know that it is not all 3, but it can be a combination of 2 or none at all..

Answer 1

1) No... if n is negative, it would always be less.
2) No... n could equal 1, and one squared is still one... so it would not be greater.
3) No... n could be any number and it will always be less (If n is 5, 2-5 = -3
Answer: None of the above.
By the way, I'm a Math teacher. How about ten points?

Answer 2

Answer is none
1) If n =-1 , 2 x -1 = -2 so is smaller than n
3) If n = 3, 2 - 3 = -1, so is smaller than n
2) If n = 1 , 1 x 1 = 1 Which is equal to n, but not greater.

Answer 3

No answer is correct . We only know that n is not =0, so n could be positive or negative. It could also be a fraction or an integer.
1)If n is negative, 2n will be an even smaller negative. Thus not the answer.
2)If n is a positive fraction less than 1, n(squared) will be smaller than n. Thus not the answer,
3)If n is positive and greater than or equal to 1, 2-n will be smaller than n. Thus not the answer.
None of these MUST be greater than n.

Answer 4

Since n is not equal to zero and assuming that can be any other integer (negative or positive number) then only 2 is correct, that is n (squared)
