Final answer:
No transformation was done to the linear parent function f(x) = x to obtain the function g(x) = x.
Step-by-step explanation:
To obtain the function g(x) = x from the linear parent function f(x) = x, there was no transformation done to the function. The function g(x) = x is exactly the same as the parent function f(x) = x. Therefore, none of the options provided (1) vertically stretched by a factor of 11, 2) shifted unit up, 3) vertically compressed by a factor of 11, 4) horizontally compressed by a factor of 11) apply.
