# Just Observe it !!!!

Algebra Level pending

Consider a function:

$$f\left( x \right) =a\log { \left( \frac { 1+x }{ 1-x } \right) } +b{ x }^{ 3 }+c\sin { x } +5$$

And it is given that $$f\left( \log _{ 3 }{ 2 } \right)=4$$, then find the value of $$f\left( \log _{ 3 }{ \left( \frac { 1 }{ 2 } \right) } \right)$$

$$\bullet$$ Here $$a$$ and $$b$$ are constants.

$$\bullet$$ Just observe closely and you will get it.....It's Easy!!!!!!!!
