Remainder = f(-1)
f(-1) = 4(-1)ⁿ - 3(-1)² + 2(-1) + 7
= 4(-1)ⁿ - 3 - 2 + 7
= 4(-1)ⁿ + 2
= 4(-1)ⁿ - 3 - 2 + 7
= 4(-1)ⁿ + 2
if n is odd ,
Then 4(-1)ⁿ + 2
= 4(-1) + 2
-4 + 2
= -2
If n is even, then 4(-1)ⁿ + 2
= 4(1) + 2
= 4 + 2
= 6
Then 4(-1)ⁿ + 2
= 4(-1) + 2
-4 + 2
= -2
If n is even, then 4(-1)ⁿ + 2
= 4(1) + 2
= 4 + 2
= 6
If n is positive and odd, then remainder of 6 is not possible
