Using translation concepts, it is found that the fourth graph(right graph of the bottom row) represents the function f(x).
What is a translation?
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is [tex]f(x) = \sqrt{x}[/tex], which has vertex at the origin.
The translated function in this problem is [tex]f(x) = 2\sqrt{x + 1}[/tex], which was vertically strecthed by a factor of 2 units(which does not change the vertex), and shifted left 1 unit, which means that the vertex is now at (0,-1).
Hence, the fourth graph(right graph of the bottom row) represents the function f(x).
