The function g(x) is a transformation of f(x)² with a vertical shift of 6 units upward.
Function g is a transformation of function f(x)².
Based on the given options, g(x) = 6 is the correct answer.
To find g(x), we need to determine the transformation applied to f(x)².
Since g(x) = 6, the transformation involves a constant shift of 6 units upward. The vertex of the transformed graph is (0, 6).
Therefore, the correct answer is g(x) = 6, which represents a vertical shift of 6 units upward from f(x)².
