Consider the leading term of the polynomial function. What is the end behavior of the graph?

2x7 – 8x6 – 3x5 – 3
(1 point)
The leading term is 2x7. Since n is odd and a is positive, the end behavior is up and up.
The leading term is 2x7. Since n is odd and a is positive, the end behavior is down and down.
The leading term is 2x7. Since n is odd and a is positive, the end behavior is down and up.
The leading term is 2x7. Since n is odd and a is positive, the end behavior is up and down.

I got the third one for the answer, I would just like to check if I got it right or not.
