Question

What is the domain of f/g if f(x)= x+9 g(x)= x-9

Answer 1

EXAMPLE: If f(x) = x2 and g(x) = x − 1, then the domain of the rational function ... EXAMPLE: If f(x) = x3 and g(x) = 3. √x, then f ◦ f = (x3)3 = x9 f ◦ g = x g ◦ f = x.

Answer 2

It cant be 9 because then the domain of g(x) would be zero
