Iterations question 12 : ) just need some

A

Step-by-step explanation:

The function is f(x) =

we need to find the value of the function when x = 3. We simply plug in 3 into x and solve.

f (3) =

This means 6 multiplied by itself 3 times. So

6 * 6 * 6 = 216

correct answer is A

(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
