f(g(x)) = √ (x 2 + 5 ) + 6
= √x 2 + 5 + 6
Now we can substitute f(x) into g(x).

the vertical shift is moving the graph up and down because this transformation involves adding a positive or negative constant
to the function.
In this case, the constant is positive (13) which will move the graph up 13 units.
the horizontal is a shift that moves the graph of the function left to right.
In this case, x+7 -> x= -7. It will move 7 units to the left.

f(x) = x + 7 + 13 is the graph of g(x) shifted up 13 units and left 7 units. The graph of f(x) is
centered at (- 7, + 13) as x can not be equal to - 7 and y can not be equal to + 13.
