Hilburn - MA509 Final Exam, Graph 6
The three points given in Exercise 6 are plotted.
A=(1,3)
B=(2,7)
C=(3,-1)
The graph of y=-6x^2+22x-13 is graphed in black.
From this representation, it is clear that the polynomial found by using Lagrange's Interpolation Formula, passes through points A, B, and C.
