The points on a section of an exam is given by the function f(x), where x is the number of questions answered correctly in that section. If f(12)=18, then a test-taker receives 18 points for answering questions in the section correctly.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

true
