Question

Determine whether each expression is a polynomial. If it is a polynomial, find the degree and determine whether it is a monomial, binomial, or trinomial. 13+y2-9 a. yes; 3; binomial ; Ob. yes; 2; trinomial Oc. yes; 3; trinomial Od. not a polynomial

Answer 1

`(1)/(5)y^3+y^2-9`

It is a polynomial.

It has 3 terms, so, it is a trinomial.

The highest exponent of y is 3, so its degree is 3.
