1、Determine which functions are polynomial functions. For those that are, state the degree. For those that are not, tell why not. x⅔ – x² + 2

Answer 1

Polynomials are defined as expressions made of terms that have a variable raised to an integer exponent.

x^2/3 - x² + 2 has a variable raised to the 2/3 power and 2/3 is NOT an integer so this expression is NOT a polynomial.
