1.) f(x) = 2x⁴ + 3x⁻² - 2x + 1 = NPF ; because of negative 2 exponent
2.) f(x) = x⁵ - x³ - 18x² - 7 = PF
3.) f(x) = x² + 3x - 7 = PF
4.) f(x) = x¹/² - 7x⁴ + 2x² - 5 = NPF ; because of non integer exponent 1/2
5.) f(x) = 3x² - 4x + 10 = PF
6.) f(x) = 3√x + 2x² - 3x + 1 = NPF ; because of √x, simplified as x¹/² which is a non integer exponent
7.) f(x) = x² + 3x + 1 + 5/x = NPF ; because of a variable x that is a denominator
8.) f(x) = 2x⁻³ + 3x² + 5x - 3 = NPF ; because of negative 3 exponent
9.) f(x) = 7x⁵ - 9x³/² + 5x - 2 = NPF ; because of non integer exponent 3/2
10.) f(x) = 5x⁷ - 3x⁴ + 2x³ - x + 6 = PF
