How do you determine if a function is polynomial?
Also to know is, what makes something a polynomial?
In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate, x, is x2 − 4x + 7.
Correspondingly, what makes a function not polynomial?
In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions. Here are some examples: This is NOT a polynomial term because the variable has a negative exponent.
Rules: What ISN'T a Polynomial Polynomials cannot contain division by a variable. For example, 2y2+7x/4 is a polynomial, because 4 is not a variable. However, 2y2+7x/(1+x) is not a polynomial as it contains division by a variable. Polynomials cannot contain negative exponents.
