Since you're already loading the tocloft package, I suggest you provide the following code in the preamble:

\usepackage{tocloft}
\renewcommand\cftloftitlefont{\mdseries\Large} % optional
\renewcommand\cftfigindent{0pt}  % no indentation
\renewcommand\cftfigpresnum{(}   % prefix "(" before figure number
\renewcommand\cftfigaftersnum{)} % affix ")" after figure number

A full MWE:

\documentclass{article}
\usepackage{newtxtext,newtxmath} % optional -- for Times-like font

\usepackage{tocloft}
\renewcommand\cftloftitlefont{\mdseries\Large} % optional
\renewcommand\cftfigindent{0pt}
\renewcommand\cftfigpresnum{(}
\renewcommand\cftfigaftersnum{)}

\begin{document}
\listoffigures

\clearpage
\begin{figure}[h!]
\caption{Three-dimensional graph}
\end{figure}

\end{document}
