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

4x5 + 1x

a)Since n is odd and a is positive, the end behavior is up and down.

b)Since n is odd and a is positive, the end behavior is down and up.

c)Since n is odd and a is positive, the end behavior is down and down.

d)Since n is odd and a is positive, the end behavior is up and up.
