$g \left(\frac{1}{3}\right)$ means that instead of $x$ you have $\frac{1}{3}$ or that your function $g \left(x\right)$ is evaluated in $x = \frac{1}{3}$, so:
$g \left(\frac{1}{3}\right) = 2 \cdot \frac{1}{3} - 5 =$ and rearranging:
$= \frac{2 - 15}{3} = - \frac{13}{3}$

This means that your function $g \left(x\right)$ has value equal to $- \frac{13}{3}$ when $x = \frac{1}{3}$
