The parent function is
g(x) = x^2
This is a quadratic function because the exponent is 2.
The transformed function is
g(x) = x^2 - 6
Recall, if a function, f(x) is translated d units downwards, it becomes f(x) - d. Thus,
g(x) = x^2 - 6 means that g(x) = x^2 was translated 6 units downwards. Thus, the correct option is
option 2
