Expert Solution
Step 1

The given function is fx=11-3x

(a)

The Maclaurin series of the function fx=11-x is as follows:

                                      11-x=1+x+x2+

which is defined for x<1, with error bound . Therefore using Maclaurin series of the above function, the Maclaurin series of  given function can be calculated as:

                                      fx=11-3x=1+3x+3x2+

Which is valid if 3x<1-13<x<13.

Hence interval of convergence is -13,13.
