1. 4

2. 2

3. 0

4. 3

EVALUATION

CONCEPT TO BE IMPLEMENTED

Polynomial

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

Degree of a Polynomial

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

EVALUATION

Here the given polynomial is

x² - 5x³ + 4x - 1

Which can be rewritten as

- 5x³ + x² + 4x - 1

Now the variable is x

Again the highest power of its variable that appears with nonzero coefficient is 3

Hence degree of the polynomial = 3

FINAL ANSWER

Hence the correct option is 4. 3
