Question

The product of 2 consecutive odd integers is 1 less than 4 times their sum. A quadratic function models this situation. What is the domain of the situation?

Answer 1

First, you must let x and (x+2) be a consecutive odd integers.
So their product will be x(x + 2)
And their sum will be 2x+2
Therefore,
x(x + 2) = 4(2x + 2) -1
Domain will be an odd integer.

I hope my answer helped you in some ways.
