Could I get some help with this one and possibly an explanation of the left and right with positive and negative

Answer:
y=f(x-4)+4
Step-by-step explanation:
This is a square root function, hence why it looks like half of a parabola that's horizontal
I suppose the red dotted line is a transformation of the original graph, [tex]y=\sqrt{x} [/tex], into [tex]y=\sqrt{x-4} +4[/tex].
The constant, 4, and -4 inside the radical changes the initial point, (h, k) of the function
