Answer:
x=18, 96-24=72, x+3x=72, 4x=72, x=18
Step-by-step explanation:
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

Answer:
Graph is attached below.
Step-by-step explanation:
If you want to solve for the variable x,
x = −4 / 5y + 7 / 5
17/8 -11/3
51/24-88/24
-37/24 simplified is -1 13/24
