    Do you remember the correlation between the highest degree of a polynomial and its end behaviour?

    would i just say down on the left and up on the right? is that correct for 1?

    could i use the infinity signs or would that not work for this??

    Or the graph is going negative when going to the left, and positive when going to the right.

    You can use infinity signs. Infinity signs would actually be more accurate.

    \[\lim_{x \rightarrow -\infty} = -\infty\]

    It is a calculus concept.
