For n odd:

1.If the leading coefficient is positive, the graph falls to the left and rises to the right.

2.If the leading coefficient is negative, the graph rises to the left and falls to the right.

For n even:

1.If the leading coefficient is positive, the graph rises to the left and to the right.

2.If the leading coefficient is negative, the graph falls to the left and to the right.

In this case, n=2, is even. Here the leading coefficent -3 is negative.
