Answer 1

Hello from MrBillDoesMath!

Answer:   domain restriction:  x <> 3, x <> -3

Discussion:

To determine the domain restriction focus on the denominator of the expression, It is x^2 - 9.  The expression is valid for all x except where x^2 - 9 = 0 as we can't dive a quantity by 0.

x^2 - 9 = 0 =>

x^2 = 9  =>

x + 3, -3

Thank you,
