Question

Can 3x^y be a polynomial?

Answer 1

never !

Answer 2

NO!

Answer 3

Because the exponent is y right? that's why?

Answer 4

polynomials never have variables in the exponents

Answer 5

This is an exponential function if anything. yeah that's right @paigeRG

Answer 6

i agree with @alffer1

Answer 7

I'd like to add, that the exponents should be whole numbers.

Answer 8

Thank you all! I was just a little confused

Answer 9

A polynomial is an expression constructed from variables (also called indeterminates) and constants (usually numbers, but not always), using only the operations of addition, subtraction, multiplication, and non-negative integer exponents (which are abbreviations for several multiplications by the same value). However, the division by a constant is allowed, because the multiplicative inverse of a non-zero constant is also a constant. For example, x2 − x/4 + 7 is a polynomial, but x2 − 4/x + 7x3/2 is an algebraic expression that is not a polynomial, because its second term involves a division by the variable x (the term 4/x), and also because its third term contains an exponent that is not a non-negative integer (3/2).
