A fifth-degree Maclaurin polynomial is used to approximate sinx. If the input is doubled from x=0.4 to x=0.8, which statement best describes the effect on the maximum possible error estimated by the Lagrange bound?
a) The error increases by a factor of 8.
b) The error increases by a factor of 32.
c) The error increases by a factor of 64.
d) The error increases by a factor of 4.
