Answer 4

a rational function is a function that is a ratio of 2 polynomial functions

Answer 5

square roots of variables are not allowed, so choice A is out

Answer 6

choice C is out because exponentials are not polynomials

Answer 7

absolute value functions are not polynomial functions, so D is out for that reason

Answer 8

Thank you

Answer 9

choice B is the only thing left

look at how 2 is a polynomial (single term expressions can be polynomials)
and how x is a polynomial

the ratio of 2 over x is a rational function
