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

Respuesta :

[tex]f(x) =log_{2}(3x-9) \\ \\g(x)=log_{2}(x-3) \\ \\ f(x) - g(x) = log_{2}(3x-9)-log_{2}(x-3)= log_{2} \frac{3x-9}{x-3}= \\ \\ = log_{2} \frac{3(x-3)}{x-3} = log_{2}3 \\ \\ f(x) - g(x) = log_{2}3[/tex]
