$\sqrt[\phantom{2}]{1+x}=1+\frac{x}{2}-\frac{x^2}{8}+\frac{x^3}{16}-\frac{5x^4}{128}+O(x^5)$

a$.(3$ points$)$ Use Matlab command to create a vector x range from $-0\mathrm{.}5$ to $0\mathrm{.}5$ with step

size of $0\mathrm{.}05.$ No need to show vector x$.$

b$.(10$ points$)$ Create a user$-$defined function $($UDF$)$ for the defined function y$($x$)$ that has

one input x and one output y$.$Name it Q$1$UDf $.$ Call this function with the

input x vector created in a$,$ name the output vector as y$\_$UDF. Copy and paste the UDF

code.
