Which one is not a polynomial? a. 4x2 + 2x − 1 b. y + 3/y c. x3 - 1 d. y2 + 5y + 1

Here are the solutions to the multiple-choice questions: Q1. Which one is not a polynomial? A polynomial must have variables with non-negative integer exponents. a. 4x² + 2x − 1: Exponents are 2, 1, 0. This is a polynomial. b. y + 3/y = y + 3y⁻¹: The exponent of y is −1, which is not a non-negative integer. This is not a polynomial. c. x³ − 1: Exponents are 3, 0. This is a polynomial. d. $y² + 5y +

Q1. Which one is not a polynomial?
A polynomial must have variables with non-negative integer exponents.

a. $4x^2 + 2x - 1$ : Exponents are 2, 1, 0. This is a polynomial.
b. $y + \frac{3}{y} = y + 3y^{-1}$ : The exponent of $y$ is $-1$ , which is not a non-negative integer. This is not a polynomial.
c. $x^3 - 1$ : Exponents are 3, 0. This is a polynomial.
d. $y^2 + 5y +
