jimthompson5910 (jim_thompson5910):

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

jimthompson5910 (jim_thompson5910):

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

jimthompson5910 (jim_thompson5910):

choice C is out because exponentials are not polynomials

jimthompson5910 (jim_thompson5910):

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

Thank you

jimthompson5910 (jim_thompson5910):

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
