3x^3 - 7x^2 + 12 - 3x^3 -6x^2 - 10x
= -13x^2 - 10x + 12
Answer is B
-13x^2 - 10x + 12
Since you don't have choices, I can only give you a description of what to look form.
The end behavior of a function is the behavior (direction) of the graph as it approaches positive or negative infinity for the domain. Basically, we are asking where is the graph going on the left side or the right side.
In the given case, as x increases the graph goes down and as x decreases the graph goes up. Look for a similar situation.
I believe the answer should be 102. It has been a long time since I have done one of these but I believe that if you times the outside angle by 2 then it is the angle if the point were to be in the center.
