Final answer:
The relationship between f(x) and g(x) given the expressions f(x)=f(x^4) and g(x)=(f(x))^4 cannot be determined without further information about the function f(x).
Step-by-step explanation:
The relationship between f(x) and g(x) cannot be determined solely based on the given information f(x)=f(x⁴) and g(x)=(f(x))⁴. The reason is that we do not have specific information about the behavior or the values of the function f(x). In order to determine whether f(x) is equal to, greater than, or less than g(x), we require additional information about the properties or the form of f(x). For instance, if it is known that f(x) is a positive function or has certain properties that determine how it behaves when raised to the fourth power, only then could we draw conclusions about the relationship between f(x) and g(x).
