Final answer:
When group functions are nested, the inner function is resolved first if it is evaluated as an argument to the outer function. However, the resolution order may vary depending on the programming language.
Step-by-step explanation:
When group functions are nested, the inner function is resolved first if it is evaluated as an argument to the outer function. This is because the inner function is executed before the outer function. However, if the inner function is not an argument to the outer function, then it may or may not be resolved first, depending on the specific programming language and its rules for function execution order.
For example, in most programming languages, the order of evaluation follows the parentheses, exponentiation, multiplication and division, and addition and subtraction (PEMDAS) rules. So, if the inner function is inside parentheses, it will be resolved first.
Overall, it is important to understand the specific programming language and its rules for function execution order to determine whether the inner function will always be resolved first when nested.
