Given the parent functions f(x) = log2 (3x − 9) and g(x) = log2 (x − 3), what is f(x) − g(x)? f(x) − g(x) = log2 (2x − 6) f(x) − g(x) = log2 (2x − 12) f(x) − g(x) = log2 one third f(x) − g(x) = log2 3

I'll get you started. You'll want to distribute the log(2) in each of the functions. Once you do that, you can easily subtract g(x) from f(x).
