Question $3$: Would like R code and explanation of the process.

Functions with multiple arguments

Write a function that takes $2$ arguments and $n)$ where $x$ is a single number and $n$ is a strictly positive

integer. The function should return the value of:

$1+\frac{x}{1}+\frac{x^2}{2}+$dots$+\frac{x^n}{n}$
