List all transformations of $LaTeX: \displaystyle f(x)=\sqrt{x}$ to obtain the graph of $LaTeX: \displaystyle g(x)=- 7 \sqrt{x + 7}+1$

The graph is reflected across the $LaTeX: \displaystyle x$ axis. The graph is stretched by a factor of $LaTeX: \displaystyle 7$ . The graph is shifted left 7 units. The graph is shifted up 1 units.
