MATLAB m-file for Mclaurin expansion

Please see the attached...

My solution to this problem differs from one I received from an OTA...
just want a second response to varify.

Thanks!

Develop a function M-file named fun_xb that evaluates the following series:

(see attachment)

where values of x and n are passed to the function through arguments. Test the function by comparing the result with hand calculations for x=1 and n=4. The foregoing series is a truncated Mclaurin expansion. (Taylor series expansion about the point x=0) of log(1+x) and converges for -1---
