degree is the exponent of the highest degree term: 8
coefficient of the leading term is the coefficient of the highest degree term: -0.6
behavior at both ends is what happens to the highest degree term, it approaches negative infinity, at both ends, as x approaches infinity or as x approaches negative infinity
neither. It's even if f(-x) = f(x). Then it's symmetric about the y axis. It's odd if f(-x) =-f(x). then it's symmetric about the origin.
It's neither and there is no symmetry
