Question
Suppose experimental data are represented by a set of points in the plane. An interpolating polynomial for the data is a polynomial whose graph
passes through every point. In scientific work, such a polynomial can be used, for example, to estimate values between the known data points.
Another use is to create curves for graphical images on a computer screen. One method for finding an interpolating polynomial is to solve a
system of linear equations. Find the interpolating polynomial p(t) = a +at+ a₂t² for the data (1,14), (2,18), (3,20). That is, find ao. a₁, and a₂
such that the following is true.
80 +8₁ (1) +8₂(1)² = 14
ao+a, (2) + a₂ (2)² =-
= 18
ao+a, (3)+ a₂ (3)2 =2
= 20
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The interpolating polynomial is p(t)=
B. There are infinitely many possible interpolating polynomials.
