Let $f:\mathbb R\rightarrow \mathbb R \backslash \{ 3\}$ be a function given by

$f(x+10)=\frac { f(x)-5 }{ f(x)-3 }$

then $\displaystyle \int _{ 10 }^{ 20 }{ f(x)\ dx }$ is equal to?

\int _{ 130 }^{ 140 }{ f(x)\ dx }

\int _{ 80 }^{ 90 }{ f(x)\ dx }

\int _{ 120 }^{ 130 }{ f(x) \ dx }

\int _{ 110 }^{ 120 }{ f(x)\ dx }

\int _{ 100 }^{ 110 }{ f(x) \ dx }
