Best ResponseYou've already chosen the best response.0A rational function is defined as the quotient of two polynomial functions. Grouping symbols are important in mathematics because they provide clarity. While, c. y=x5/x appears to be the answer, it is not clear if c) mean y = (x  5)/x or y = x  (5/x) which could be converted to y = (x^25) / x. I suppose that either interpretation leads to a rational function although grouping symbols would dissolve the ambiguity here.
