Question 77394
End behavior of of each graph of the polynomial.. 
-6d^3 -4d^2 +2d -1 
--------
You may be right but that is not the way it is normally stated.
The graph goes to negative infinity as d goes to positive infinity because of
the -6d^3 term.
-------
The graph goes to + infinity as d goes to negative infinity for the 
same reason.
