Can you guys pls help i’m so lost

Step-by-step explanation:

f(x) = sqrt(x-4)

Domain is x>= 4 because when x<4, then x-4 becomes negative, and square of negative numbers is not in the real domain.

f(10) = sqrt(10-4) = sqrt(6) = 2.45

f(6) = sqrt(6-4) = sqrt(2) = 1.41

f(12) =sqrt(12-4) = sqrt(8)   = 2.28

f(19) = sqrt(19-4) = sqrt(15) = 3.87

(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

divide by no of mode
