What does the notation (f/g)(x) represent?

• A. The addition of two functions
• B. The division of two functions
• C. The multiplication of two functions
• D. The subtraction of two functions

Answer: (B)

The notation (f/g)(x) indicates the division of two functions, f(x) and g(x). When you see this notation, it specifically means that you take the output of the function f at x and divide it by the output of the function g at x. This can be expressed mathematically as (f/g)(x) = f(x) / g(x). In functional notation, "/" denotes division, which is why this notation is used to represent the division of the two functions rather than any other operations like addition, multiplication, or subtraction. Each of those operations has its own distinct notation in function representation, such as using "+" for addition, "*" or juxtaposition for multiplication, and "-" for subtraction. Understanding this functional notation is crucial for effectively working with multiple functions and performing operations such as addition, subtraction, multiplication, or division accordingly.
