We have to make two transformations to the parent square root function:
a) Reflection across x-axis
b) Vertical shift by 3 units upwards
Applying first transformation the result will be:
[tex]- \sqrt{x} [/tex]
Applying the second transformation,the result will be
[tex]- \sqrt{x} +3[/tex]
The above expressions gives the graph of [tex]\sqrt{x} [/tex] which is reflected across x-axis and is shifted upwards by 3 units
