Which is bigger? (Bryan Goh, Ryan Ng, Chelsea, Xue Qin)

If n is smaller than 5, 5n > n^2

However if n is negative, 5n < n^2.

If n is equals to 5, 5n = n^2

If n is larger than 5, 5n < n^2

Which is bigger? Qayyum

5n will be bigger than n^2 unless the value of n is more than 5. If the value of n is 5 then both will be equal. If the value of n is less than 5 than 5n will be bigger than n^2.

For example, if the value of n is 6 then 5n will be 30 and n^2 will be 36.
If the value of n is 5 then both values will be 25.
If it is 4 than 5n will be 20 and n^2 will be 16.

Given the following please post a new post as to whether they are (i) equal  (ii) one greater than the other. Provide a good proof for this (hint: refer to previous activity). Collaborate with the members of the same group as in the ICT activity.

Question:  Is 5n  > or =  n^2 ?
