ANSWER
Option D
EXPLANATION
The parent radical function is
[tex]f(x) = \sqrt{x} [/tex]
The transformed function is
[tex]g(x) = 2 \sqrt{x - 3} [/tex]
This is a transformation of the form.
[tex]y = a \sqrt{x - k} [/tex]
which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.
In this case a=2 and k=3,
there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.
The last choice is correct.
