is f(x)=13 a polynomial function?
Ans: f(x)=13 is a constant function. A constant is a very special (constant) polynomial, with no dependence on x. So technically it is not wrong to say that f(x)=13 is a polynomial function !

the degree of a polynomial is the highest exponent of any variable in the polynomial. the first one has a term which is -2x^2*x*x which is -2x^4 the exponent is 4; so is the degree. 4(x+3)^3 has an x^3 term, ergo degree 3 i dont know if that helped, but as a rule for determining the degree, the first thing to do is to multiply your polynomial out. that it's multiply the factors together until you have no parentheses. then order the terms in descending order, meaning the first term is ax^n, the second is bx^(n-1), and the last term is some constant c now it's easy: the degree is n. by the way, having done all of that, you're also ready to do a bunch of other useful polynomial things.

Actually, its a horizontal line. x = 13 would be a vertical line. It is a polynomial, buts its degree is zero. A second degree polynomial would be like f(x) = 13 x^2, a first degree polynomial would be like f(x) = 13 x, and a zero degree polynomial would be like f(x) = 13, because x to the zero power is one.

This is not a function at all because there is no variable involved your really just saying that y=13.
The notation f(x) implies a function but it incorrect because to equal a numerical value there must have been some input.
This is a line with a constant value but not a polynomial.

No. Since there are no variables.
In mathematics, a polynomial is an expression that is constructed from one or more variables and constants, using only the operations of addition, subtraction, multiplication, and constant positive whole number exponents. is a polynomial. ...

Absolutely. A constant is a polynomial of degree 0.
If it helps, think of it as f(x) = 13x^0

No, it is monomial. Polynomials require operators such as addition, subtraction, or division.
f(x) = x + 13 is polynomial
It doesn't need more than one variable, just more than one term.
F(x) = x + x^2 is also polynomial

no a polynomial means more then 2 numbers...

You can't tell, since f(x) is not defined. A polynomial means that f(x) is composed of two or more terms.

no, a polynomial is a function with more than one variable, such as:
f(x):2x+4y=c
