ANSWER


The correct answer is option D.


EXPLANATION


The given function is



[tex]k(x)=-3x^6-0.7x+x^3[/tex]



This a polynomial function. All degrees are greater than or equal to zero.


The coefficient being decimals does not disqualify it from being a polynomial.


The highest degree of this polynomial is 6.


Therefore the correct answer is D
