f(x)=x/x^2+2

f(-x)=-x/-x^2+2
f(-x)=-x/-x*-x+2

f(-x)=1/-x+2

F(x)=x/x²+2

So... f(x)=1/x+2

Therefore:

f(-x)=1/(-x)+2=-1/x+2

Answer:

$-\frac{39}{10}$

Step-by-step explanation:

$\frac{-\frac{1}{6}}{\frac{1}{9}} - \frac{12}{5}\\\\-\frac{1}{6}\cdot \frac{9}{1} - \frac{12}{5}\\\\-\frac{3}{2} - \frac{12}{5}\\\\-\frac{39}{10}$

Some things you have to keep in mind to solve this problem

$\frac{a}{\frac{b}{c}} = \frac{a}{b}\cdot \frac{1}{c}$

And also you have to know how to subtract fractions, if you don't please let me know and I'll try to give you a hand.

Good luck!
