Question
Let P(x) be the fifth-degree Taylor polynomial for a function f about x=0. Information about the maximum absolute value of
selected derivatives of f over the interval 0<xs1.2 is given in the table below:
max f (x) = 8.4
0<x<1.2
(5)
max
0<x<1.2
|F® (x) = 58.8
max f (x) = 411.8
0<x<1.2
If f(1.2) were approximated using P(1.2), what is the maximum error bound given by the Lagrange Remainder formula?
