The Polynomial $f$ Graphed Below Has Leading Term $a x^{n}$ (IE $f(x)=a x^{n}+$

Short Answer

The polynomial $f$ graphed below has leading term $a x^{n}$ (i.e. $f(x)=a x^{n}+$ terms of lower degree). We know that $a$ is ----------- (positive \ negative), $n$ is ------------- (even \ odd), and the smallest possible value of $n$ is ----------------------.
