WebComposition of functions is the process of plugging one function into another, and simplifying or evaluating the result at a given x -value. Suppose you are given the two functions f(x) = 2x + 3 and g(x) = −x2 + 5. Composition means that you can plug g(x) into f(x), (or vice versa). canfd フレームフォーマットWeby=\frac{x}{x^2-6x+8} f(x)=\sqrt{x+3} f(x)=\cos(2x+5) f(x)=\sin(3x) functions-calculator. en. image/svg+xml.

In this case, if you had functions defined, f (x) and g (x), then to get (f ∘ g) (x) you would substitute g (x) for x inside of f (x). Another way to write it is f (g (x)).
