Root - crowlogic/arb4j GitHub Wiki

In mathematics, the root of a function, also known as a zero or a solution, is a value of the input variable (often denoted as x) for which the function outputs a value of zero. In other words, if you have a function f(x), a root of the function is a value x = a, such that f(a) = 0.

Roots are important in various branches of mathematics and have applications in solving equations, analyzing the behavior of functions, and optimizing processes in fields such as engineering and economics.

For example, if you have a quadratic function f(x) = x^2 - 5x + 6, the roots of this function are the values of x that make the function equal to zero. In this case, the roots are x = 2 and x = 3, since f(2) = (2)^2 - 5(2) + 6 = 0 and f(3) = (3)^2 - 5(3) + 6 = 0.
