Answer:
As x-> -∞, y->∞
x-> ∞, y->-∞
Leading term -3x^5
Explanation:

Leading term is the first term of the polynomial
Leading term -3x^5
The exponent of leading term is 5 that is odd
and the coefficient of leading term is -3 that is negative
When the coefficient of leading term is negative and exponent of leading term is odd then the graph goes up on the left and goes down on the right.
As x-> -∞, y->∞
x-> ∞, y->-∞
Leading term -3x^5
