ANSWER
The graph of the function starts from (1,4) and moves up right.
EXPLANATION
The given rational function is
[tex]y = \sqrt{x - 1} + 4[/tex]
The base of this function is
[tex]y = \sqrt{x} [/tex]
The -1 under radical sign means the graph of the base function is shifted 1 unit right.
The +4 shows that base function is shifted up by 4 units.
The graph of the function therefore starts from (1,4) and moves up right.
