- Yields the
*n*^{th}intersection point of the polynomial and the line. - Intersect[<Function f>, <Function g>, <Point A>]
- Calculates the intersection point of functions
*f*and*g*by using a (numerical) iterative method with initial point*A*. - Intersect[<Function>, <Line>, <Point A>]
- Calculates the intersection point of the function and the line by using a (numerical) iterative method with initial point
*A*. - Intersect[<Function f>, <Function g>, <left-x>, <right-x>]
- Calculates the intersection points for the two functions in the given interval.

**Note:**Also see tool Intersect Two Objects.

- Intersect[ <Line>, <Parametric Curve>]
- Yields the intersection points of a line and a parametric curve.
**Example:**`Intersect[y = x + 3, Curve[t, 2t, t, 0, 10]]`
