Consider the graph of $f\left(x\right) = \operatorname{sin}\left(x\right)$.

1. Describe the graph.

   Hint (a):

   In general terms, what does it look like?

2. Could this graph be an example of any other function? Explain why f(x) = sin(x) cannot be a polynomial function.

   Hint (b):

   How many roots does$f\left(x\right) = \operatorname{sin}\left(x\right)$ have?
