Question

Identify the variable expression that is not a polynomial.

A. y+23
B. 3\sqrt(x)-2
C. x^3
D. 13

Answer 1

B. 3\sqrt(x)-2

Explanation:

A polynomial cannot have a variable in the denominator

A constant is a polynomial

3\sqrt(x)-2 and this cannot be simplified to get rid of the variable in the denominator so it is not a polynomial
