Numerical methods for ﬁnding the roots of a function The roots of a function f(x) are deﬁned as the values for which the value of the function becomes equal to zero. So, ﬁnding the roots of f(x) means solving the equation f(x) =0. Example 1: If f(x) =ax2+bx+c is a quadratic polynomial, the roots are given by the well-known formula.

Numerical stability is a notion in numerical analysis. An algorithm is called 'numerically stable' if an error, whatever its cause, does not grow to be much larger during the calculation. This happens if the problem is ' well-conditioned ', meaning that the solution changes by only a small amount if the problem data are changed by a small amount.
