Unformatted text preview: nterpolating polynomial. Type help axis at the Matlab
prompt and read the resulting helpﬁle to learn how to use this important command. You
can also use the zoom tools in the ﬁgure window’s toolbar to highlight regions of interest. The
Interpolating
Polynomial If a system of linear equations has more equations than unknown variables, then the system is
overdetermined. An overdetermined system may or may not be consistent.
2. 3. Find a second degree polynomial (if one exists) that passes through the points (−2, −7.6),
(−1, −7.8), (1, −1.0), (2, 6.0), and (3, 15.4). If the interpolating polynomial exists, obtain a
plot that contains both the data points and the interpolating polynomial. If the interpolating
polynomial doesn’t exist, obtain a plot of the data points and explain why there can be no
second degree polynomial that passes through the points.
Find a second degree polynomial (if one exists) that passes through the points (−3, 1),
(−1, 4), (1, 2), and (2, 6). If the interpolating polynomial exists, obtai...
