The function satisfies $f(x+y) = f(x)f(y)$ for all real $x,y$. What is the difference between f (x) and y? There is no difference between "f (x)" and "y". The notation "f (x)" means exactly the same thing as "y". You can even label the y-axis on your graphs with "f (x)", if you feel like it. It doesn't matter if you're graphing y=, looking at Y1= in your calculator, or plugging x-values into f(x)=; they ...Aug 4, 2018 · f(x) = 1 f ( x) = 1. f(x) = 0 f ( x) = 0. However, these solutions are family solutions of f(x) =xn f ( x) = x n. What I meant by this is that, when n = 1 n = 1 you get the function f(x) = x f ( x) = x. When n = 0 n = 0 you get f(x) = 1 f ( x) = 1 and when x = 0 x = 0 well you get f(x) = 0 f ( x) = 0 . So, it seems f(x) =xn f ( x) = x n is the ...

Y: the outcome or outcomes, result or results, that you want; X: the inputs, factors or whatever is necessary to get the outcome (there can be more than one possible x) F: the function or process that will take the inputs and make them into the desired outcome; Simply put, the Y=f(x) equation calculates the dependent output of a process given ...

That is, the functions f : X → Y and g : Y → Z are composed to yield a function that maps x in domain X to g(f(x)) in codomain Z. Intuitively, if z is a function of y, and y is a function of x, then z is a function of x. The resulting composite function is denoted g ∘ f : X → Z, defined by (g ∘ f )(x) = g(f(x)) for all x in X.
