- Root[Polynomial]
- Yields all roots of the polynomial as intersection points of the function graph and the
*x*‐axis. - Root[Function, Number a]
- Yields one root of the function using the initial value
*a*for Newton's method. - Root[Function, Number a, Number b]
- Yields one root of the function in the interval [
*a, b*] (regula falsi).
