The leading term of polynomial function is the the term contain highest degree so here in the given question leading term is 
and leading coefficient is the coefficient of the term with greatest exponent -3
RULES for End behaviour
we have following four cases
CASE1: Even degree and positive leading coefficient


CASE2: Even degree and negative leading coefficient


CASE3: Odd degree and positive leading coefficient


CASE4: Odd degree and negative leading coefficient

Here in the given case we have odd degree and negative leading coefficient

3,322.609847222222 mph. First covert miles to km. This distance is 239227.909 miles. then divide this by the number of hours which is number of days times 24. It took 3 days so it is 72 hours. After diving 239227.909/72 you get your answer of 3,322.609847222222 mph
Answer:
m=-9+n
Step-by-step explanation:
you want to get m by itself so you subtract 9 on both sides. 9-9 crosses out and you get m by itself. Which leads you to m= -9+n
