Answer
See below.
Work Step by Step
The leading coefficient test says that :
-if the leading power is odd and the leading coefficient is positive, the graph falls to the left and rises to the right
-if the leading power is odd and the leading coefficient is negative, the graph falls to the right and rises to the left
-if the leading power is even and the leading coefficient is positive, the graph falls to the left and falls to the right
-if the leading power is even and the leading coefficient is negative, the graph falls to the right and falls to the left
Hence here $x^3$'s graph falls to the left and rises to the right. (see graph)
