- Roots[ <Function>, <Start x-Value>, <End x-Value> ]
- Calculates the roots for function in the given interval. The function must be continuous on that interval. Because this algorithm is numeric, it may not find all the roots in some cases.
- Example:
Roots[f, -2, 1]with the functionf(x) = 3x³ + 3x² - xyieldsA = (-1.264, 0), B = (0, 0), C = (0.264, 0)
