Question 1208424: Determine if the expressions are polynomials. If it is, give its degree. If it is not, state why not.
A. 1 - 4x
Polynomial
The degree is 1
B. -pi
I am not sure about B. I say it is a polynomial because it can be expressed as -pi•x^(0). Yes?
C. (3/x) + 2
This is not a polynomial. It is a rational expression. Yes?
D. 10z^2 + z
Yes, a polynomial
The degree is 2
E. (3x^3 + 2x - 1)/(x^2 + x + 1)
I say E is not a polynomial. This is a rational expression.
You say?
