Question

In a polynomial, the exponents of the variables are always:

• A. Integers
• B. Non - negative integers
• C. Positive integers
• D. Non - positive integers

Answer 1

The correct option is B

Non - negative integers

Non - negative integers include 0 and positive integers. Polynomials cannot have variables with exponents as negative integers or rational numbers.
For example, $(5y+z+xz+x^{3}yz),(x+2x^2+2x-1$) etc are polynomials, whereas $x^{-2},(2x^{-3}+x^{-1}+4$) are not.
