First put it in decreasing power according to x.
x^4-5x+8+x^2
=x^4+x^2-5x+8
Now this question is asking what is the highest degree of x you see in this function.
4 of course.
Therefore the answer to his question is degree of 4.
Done!
Solution
The range is defined as:
Range = Max - Min
For this case we can conclude that the best solution would be:
B, C
