Question

X+ 5 If m(x) = X-1 and n(x) = x - 3, which function has the same domain as (m×n(x)?​

Answer 1

Lets start off by clearing up the question,

I'm assuming it's asking m(x) * n(x). Doing so will make you foil it, giving you a quadratic/ polynomial.

Because it is a polynomial, we can assume all real numbers are defined. So really any poly works.

Edit: To clarify, you can make any quadratic equation and it will have the same domain as any polynomial is defined. So for example: x^2 + 2x + 5 works.
