is -13 a polynomial?

Question

and if an equation has pi in it can it be a polynomial like x^3y^2-pi

Answer 1

Hey there!

Yes. -13 is a polynomial since it can be rewritten as -13x^0, making it a polynomial.

Any expression in the form of x^n+x^(n-1)+x^(n-2)..., where x is a variable and n is the constant is a polynomial.

Hope it helps!

Answer 2

An expression containing pi can be a polynomial if pi is a coefficient of a non-negative power of the variable, but not if pi is an exponent on the variable.

Answer 3

Yes,-13 is a polinomial of order zero.
