Let $\mathrm{y}=\mathrm{g}(\mathrm{x})$ be the inverse of a bijective mapping $\mathrm{f}:\mathrm{R}\to \mathrm{R}$ defined as $\mathrm{f}(\mathrm{x})=3x^3+2x$. The area bounded by the graph of $\mathrm{g}(\mathrm{x})$, the x -axis and the coordinate at $\mathrm{x}=5$ is 'A' then the value of

(4A -7) is
