Identify the function that is not linear a. y=5 -3^x b. 4y= 16 c. y=5 d. 5y=25

The only function that is not linear is a) y = 5 - 3^x

Step-by-step explanation:

In this case, the variable is in the exponent. This makes the function curve, therefore it is not linear.

(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
