This video tutorial explains how to denote a function using function notation. It begins by identifying a relation as a function and then demonstrates how to use function notation by replacing 'y' with 'f(x)'. The tutorial clarifies that 'f(x)' is the output when 'x' is the input and addresses common misconceptions, such as confusing 'f(x)' with multiplication. It also highlights that function notation can use various letters, not just 'f(x)'.
