Question

Write all of the following statement(s) that apply to the following polynomial: -x^4 +7x^5+2

It is a trinomial.
It can be evaluated at x= -1/3
It has a coefficient of 1.
It is quadratic.

Is this the correct answer:
It is a trinomial.
It can be evaluated at x=-1/3
-(-1/3)^4 +7(-1/3)^5 +2
=1/3^4 - 2 1/3^5 +2
=1/81 - 69 40/243 +2
= -67 37/243

Thanks for the help!
