#### Answer

See graph and explanations.

#### Work Step by Step

Step 1. Graph the function together with $y=sin(x)$ as shown in the figure. Step 2. Compared to $y=sin(x)$, we can see that the given function follows the general shape of $sin(x)$ with modulations due to the extra fractional terms. Step 3. We can also see that a new periodic function is formed with the same period, but has shifts in the minimum and maximum positions from $y=sin(x)$.
