ANSWER:

[tex](\frac{1}{2},\infty)[/tex]

EXPLANATION:

Remember that any logarithm is capable of recieveng numbers that are greater than zero. This way, we'll have the restriction:

[tex]2x-1>0[/tex]

Solving for x,

[tex]\begin{gathered} 2x-1>0 \\ \rightarrow2x>1 \\ \\ \Rightarrow x>\frac{1}{2} \end{gathered}[/tex]

This way, the domain is:

[tex](\frac{1}{2},\infty)[/tex]
