Which expression is equivalent to \( \left(\frac{3}{2}\right)^{3} ? \)

Which expression is equivalent to \( (2 \cdot 6)^{3} ? \)

1) \( f(x)=\log _{2} \quad x+2 \) 2) \( f(x)=\log _{2} \quad x-1 \) 3) \( f(x)=\log _{2} \quad x+3 \) 4) \( f(x)=\log _{2}(x+2) \) 5) \( f(x)=\log _{2}(x-2) \) 6) \( f(x)=\log _{2}(x-5) \)
