## Algebra 2 (1st Edition)

The given functions are sine and cosine functions in the form $y=asin(bx)$ and $y=acos(bx)$. Note, the only difference between sine and cosine functions is that, when not shifted, cosine functions are at their maximum amplitude at $x=0$, while sine functions are at $0$ at this point. Note, $\mid a\mid$ is the amplitude of the functions, and $\frac{2\pi}{b}$ is the period of these functions. Knowing this, we can create the graph.
