Answer: It depends on on what number you plug in for N. If N is even, the answer is odd. If N is odd, the answer is even.
Step-by-step explanation:
What I did is plug in an even and odd number. I plugged in 3 as the odd number. This gets me 3^2 -1. 9-1+8. Therefore the answer is even.
If you plug in 2, you get 2^2 -1 which gives you 4-1+3. The answer here is even.
