Answer:
D. Quartic trinomial
Step-by-step explanation:
Given polynomial:
[tex]3x^4+x+7[/tex]
We can make following conclusions for the given polynomial.
1) The polynomial has three terms including a constant term. Thus it is a trinomial as trinomials are polynomials with 3 unlike terms.
2) The leading term is [tex]3x^4[/tex] as it is the highest degree term..
3) The degree of polynomial is 4 as leading variable [tex]x[/tex] in the leading term is raised to power of 4. Thus, it is a quartic polynomial as it is of degree 4.
Thus, this polynomial can be called a quartic trinomial.
