## Main Question or Discussion Point

for g(x) = (x-2) / (x^2 -9)

the domain of the function would be simply to have the denominator not equal to 0, which in this case would be x = 3.

but.. the solution states that it is

this is confusing seeing that -3^2 -9 = -18 which is not 0.

maybe it means |-3|?

**-3**and 3 cannot be used.this is confusing seeing that -3^2 -9 = -18 which is not 0.
