List all transformations of $LaTeX: \displaystyle f(x)=\sqrt{x}$ to obtain the graph of $LaTeX: \displaystyle g(x)=- 4 \sqrt{x - 8}+7$

The graph is reflected across the $LaTeX: \displaystyle x$ axis. The graph is stretched by a factor of $LaTeX: \displaystyle 4$ . The graph is shifted right 8 units. The graph is shifted up 7 units.
