WebDec 8, 2014 · When we are working with a specific x value, we can suggestively write f ( h ( x)) instead. ( f ∘ h) ( x) = f ( h ( x)) = f ( 2 + 3 x) = 1 2 + 3 x. (Note: I only used z as the variable for f to avoid confusion; in practice the function does not care what its input variable is named.) The circle ∘ is the symbol for composition of functions.
