To find the compositions of the functions \( f(x) \) and \( g(x) \): 1. **Finding \( f(g(x)) \)**: \[ g(x) = \frac{6}{x} + 2 \] Now substituting \( g(x) \) into \( f(x) \): \[ f(g(x)) = f\left(\frac{6}{x} + 2\right) = \frac{1}{\left(\frac{6}{x} + 2\right) - 2} \] Simplifying the expression: \[ f(g(x)) = \frac{1}{\frac{6}{x}} = \frac{x}{6} \] 2. **Finding \( g(f(x)) \)**: \[ f(x) = \frac{1}{x - 2} \] Now substituting \( f(x) \) into \( g(x) \): \[ g(f(x)) = g\left(\frac{1}{x-2}\right) = \frac{6}{\frac{1}{x-2}} + 2 \] Simplifying the expression: \[ g(f(x)) = 6(x - 2) + 2 = 6x - 12 + 2 = 6x - 10 \] Thus, the answers are: \[ f(g(x)) = \frac{x}{6}, \quad g(f(x)) = 6x - 10 \]
