what is a function in math

Let us learn about what is a function in math

A function f from N → N is referred by f(x) = 3x. Find the range of f.

Solution: f = {3, 6, 9, 12, …}

Given f(x) = 4x/(x +1) with domain (–3, –2, 0, 1, 3}. Find the range of f.

Solution: The range of f is (6, 8, 0, 2, 3}

A math function is a 1 of the type of relation. In a function, number two ordered pairs can have the same 1st element & a different 2nd element. That is, for functions, corresponding to every 1^st element of the ordered pairs, there must be a different 2^nd element. That is. In a function we can't have ordered pairs of the form (a₁, b₁) & (a₂, b₂) with a₁ = a₂ & b₁ ≠ b₂. It is called as function in math
