How do you extrapolate a polynomial?

Polynomial extrapolation is typically done by means of Lagrange interpolation or using Newton's method of finite differences to create a Newton series that fits the data. The resulting polynomial may be used to extrapolate the data. High-order polynomial extrapolation must be used with due care.

What is extrapolation formula?

Extrapolation Formula

Let us consider the two endpoints in a linear graph (x₁, y₁) and (x₂, y₂) where the value of the point “x” is to be extrapolated, and then the extrapolation formula is given as. y ( x ) = y 1 + x − x 1 x 2 − x 1 ( y 2 − y 1 )

What is interpolation and extrapolation formula?

Linear interpolation is a mathematical method of using the equation of a line in order to find a new data point, based on an existing set of data points. Linear extrapolation is the same as linear interpolation, with the exception of the new data points, which are outside the range of the given (known) data points.

How do you calculate extrapolation data?

Extrapolation Formula

m=y−y1x−x1 m = y − y 1 x − x 1 .
