#### Answer

The graph shown should have undergone a combination of the transformations of $g(x) = \sqrt{x}.$
The equation of the graph is $y = \sqrt{x-1} - 3.$

#### Work Step by Step

As there is no sign of any symmetry across neither the $x$-axis nor the $y$-axis, the graph shown should have undergone a combination of the transformations of $g(x) = \sqrt{x}$.
Since horizontal translation to the right by 1 unit is found, $x$ should be replaced by '$x-1$' and vertical translation down by 3 units is shown, a value of '3' should be deducted.
Hence, the equation of the graph is $y = \sqrt{x-1} - 3.$
