Answer:
Option 1.
Step-by-step explanation:
If the degree of a polynomial is even and leading coefficient is positive, then


If the degree of a polynomial is even and leading coefficient is negative, then


If the degree of a polynomial is odd and leading coefficient is positive, then


If the degree of a polynomial is odd and leading coefficient is negative, then


Given end behavior is described by a polynomial whose degree is odd and leading coefficient is positive.
Only the function
has odd degree and positive leading coefficient.
Therefore, the correct option is 1.
