Describe the Transformations and Give the Equation for the Graph $f ( x ) = \sqrt { x }$

Describe the transformations and give the equation for the graph.

A) It is the graph of $f ( x ) = \sqrt { x }$ translated 4 units to the right, shrunken vertically by a factor of $\frac { 1 } { 2 }$ and translated 3 units up. The equation is $y = \frac { 1 } { 2 } \sqrt { x + 4 } + 3$
B) It is the graph of $\mathrm { f } ( \mathrm { x } ) = \sqrt { \mathrm { x } }$ translated 4 units to the right, stretched vertically by a factor of 2 and translated 3 units up. The equation is $y = 2 \sqrt { x - 4 } + 3$
C) It is the graph of $f ( x ) = \sqrt { x }$ translated 4 units to the right, stretched vertically by a factor of 2 and translated 3 units up. The equation is $y = 2 \sqrt { x + 4 } + 3$
D) It is the graph of $f ( x ) = \sqrt { x }$ translated 4 units to the right, shrunken vertically by a factor of $\frac { 1 } { 2 }$ and translated 3 units up. The equation is $\mathrm { y } = \frac { 1 } { 2 } \sqrt { x - 4 } + 3$
