4.3: Numerical Approximation of Roots of Functions

WebLet f be a real single-valued function of a real variable. If f(α) = 0, then α is said to be a zero of f or null or, equivalently, a root of the equation f(x) = 0.It is customary to say that α is a root or zero of an algebraic polynomial f, but just a zero if f is not a polynomial.
