Final answer:
Due to lack of context or additional information, it is not possible to calculate the value of d from the provided functions.
Step-by-step explanation:
It seems there is some confusion in the question presented as it is not clear how the functions are related to each other or to the calculation of constant d. To find the value of d in the function g(x) = 4x + d, we need additional information about how this function relates to other given functions or additional conditions or equations. If the student has provided more context or if there is a specific relationship between the functions that allows us to solve for d, such as F(x), g(x), or a composite of the two, it could be possible to find the value of d. However, based on the current information, we cannot solve for d without more details or further instructions on the relationship between the functions.
