Which of the following notations correctly describe the end behavior of the polynomial graphed below?

Option A is correct.

Step-by-step explanation:

We can clearly see from the graph that whenever the graph is tending to negative function will be positive

And if x tends to positive the function will be positive.

So, from the options if we choose option A matches the behavior of the graph

Therefore, Option A is correct.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
