Final answer:
Function arguments in programming are enclosed in parentheses ( ). This is a common practice across multiple programming languages, similar to how parentheses are used in English to include additional information.
Step-by-step explanation:
Function arguments are enclosed in a pair of parentheses ( ). When you are using functions in programming, it is standard to place the arguments that you are passing to the function within parentheses directly after the function name. This is a rule that is common across many programming languages. The use of parentheses in this context is similar to their use in other areas. For example, in English writing, parentheses are often used to include additional, nonessential material, such as dates or clarifying information within a sentence, in order to provide further explanation without overwhelming the main text.
