Answer
See the graph below.
Work Step by Step
The function $y=x^2+\frac{1}{50}cos(100x)$ is the sum of two functions $y=x^2$ and $y=\frac{1}{50}cos(100x)$ which has an amplitude of $|a|=\frac{1}{50}$ and a period of $p=\frac{\pi}{50}$. Thus, the graph window needs to be adjusted to show all the features.
