Final answer:

Due to an apparent typo in the function A(x) = -2 - 4x% - 7 + 1, where '4x%' is unclear, we cannot definitively state the range. We assume that 6 is in the domain of f(x) since it's a real number and the function seems linear, but we cannot confirm if 6 is in the range or not, though option 'a)' is suggested with caution.

Step-by-step explanation:

The given function f(x) is assumed to be A(x) = -2 - 4x% - 7 + 1, although this contains what appears to be a typo with '4x%'. Assuming '4x%' means '4x', the correct expression of the function would likely be A(x) = -2 - 4x - 7 + 1. To determine the domain and range of this function, we can analyze its form. This appears to be a linear function without restrictions on x, therefore, any real number can be input into the function, meaning 6 is in the domain of f(x). However, without the ability to correctly interpret the given function, specifically due to '4x%', we cannot confidently determine if 6 is in the range or not. Since we cannot verify the range, the only option left considering the domain is 'a) 6 is in the domain of f(x) but not in the range of f(x).', but this is not a definitive answer and should be taken with caution due to the ambiguity arising from the typo.
