Question 1206747
<br>
The domain of any polynomial function is all real numbers, so answer choices A and C are not right.<br>
The graph is an upward opening parabola, so the range is all real numbers greater than or equal to some minimum value.  So between the remaining answer choices B and D, answer choice D can't be right.<br>
Since one of the answer choices has to be right, it must be B.<br>
We could do some work with the given equation to verify that the minimum value is -8; but with only four answer choices of which three can't be right, we shouldn't need to do that.<br>
ANSWER: B<br>
