In mathematics, function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x))In this operation, the function g is applied to the result of applying the function f to xThat is, the functions f X → Y and g Y → Z are composed to yield a function that maps x in X to g(f(x)) in Z Intuitively, if z is a function of y, and y is aL b N X ̗ K ē ܂ I S t A W X g ւ悤 I price down item;Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, history

Definition A sequence of functions fn X → Y converges uniformly if for every ϵ > 0 there is an Nϵ ∈ N such that for all n ≥ Nϵ and all x ∈ X one has d(fn(x), f(x)) < ϵ Uniform convergence implies pointwise convergence, but not the other way around For example, the sequence fn(x) = xn from the previous example converges pointwise
