TraditionalFunctionNotation
is an option for selections that specifies whether input of the form 
is interpreted by the kernel as a function or as a product.
Details
- By default TraditionalFunctionNotation->True for TraditionalForm. This means that input of the form
is interpreted as a function f of the variable x. - For StandardForm, TraditionalFunctionNotation->False by default. This means that input of the form
is interpreted as a product of the variables f and x.
