Final answer:
The graph of (f°g)(x) is the graph of the function f(x) = √x.
Step-by-step explanation:
The composite function (f°g)(x) is obtained by plugging in the function g(x) into the function f(x). In this case, g(x) = x, so we substitute x into f(x) to get:
f(g(x)) = f(x) = √x
Therefore, the graph of the composite function (f°g)(x) is the graph of the function f(x) = √x.
