Use Properties of Logarithms to Condense the Logarithmic Expression $$\log _ { 4 } ( x - 3 ) - \log _ { 4 } ( x + 1 )$$

Multiple Choice

Use properties of logarithms to condense the logarithmic expression. Write the expression as a single logarithm whose coefficient is 1. Where possible, evaluate logarithmic expressions.
- $$\log _ { 4 } ( x - 3 ) - \log _ { 4 } ( x + 1 )$$

A) $\log _ { 4 } \left( \frac { x - 3 } { x + 1 } \right)$
B) $\log _ { 4 } \left( x ^ { 2 } - 2 x - 3 \right)$
C) $\log _ { 4 } \left( \frac { x - 3 } { x - 1 } \right)$
D) $\log _ { 4 } - 4$
