Question

Can somebody please help me? let f(x)=1/x and g(x)=x^2-2x. what two numbers are NOT in the domain of f g?

Answer 1

looks like f(g(x)).

f(g(x)) = 1/g(x)

so g(x) can not be 0.

that is, not(g(x) = 0)

Answer 2

Can you please separte it using a comma?

Answer 3

\[g(x) \neq 0\]

Answer 4

x^2 - 2x ≠ 0
x(x-2) ≠ 0

x≠0 and x≠2

Answer 5

Thank you!
