Answer:
Option B and D are correct.
Step-by-step explanation:
Given the function: 
End behavior states that a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity.
As
in the given function, then 
and
As
in the given function, then 
Therefore, as x increases without bound , f(x) decreases without bound
and as x decreases without bound , f(x) approaches the line y =-2
