WebSep 12, 2011 · What is f(x)? It is a different way of writing "y" in equations, but it's much more useful! Webf (x) means: a function called ‘f’ which takes an input of ‘x’. Please note that y = f (x) is nothing magical. ‘f’ is just the name of the function, ‘x’ is just the function’s input and ‘y’ is just the function’s output. So y = f (x) means: a …

WebJun 14, 2016 · No. They have no special significance. All of these are simply used by convention to refer to a function. For example, f(x)=e^x, a(x)=e^x, and z(x)=e^x all mean the same thing. However, some notations mean only one thing. For example, zeta(s) refers to the Riemann zeta function: sum_(n=1)^oo1/n^s (See this link for more info: Riemann … WebIn this video we learn about function composition.
