Which of the following is written as a rational function

A. Q (x) = x^2+5x-6

B. F (x) = x-3/8x

C. G (x) = - 5x

D. P (x) = 2x+3

Answer

B. F (x) = x-3/8x

Step-by-step explanation:

A rational function is a function that is a fraction and contains a property that both its numerator and denominator are polynomials.

This is to say F (x) is a rational function if R (x) = p (x) / q (x) where p (x) and q (x) are both polynomials

A polynomial is an algebraic expression which consists of one, two or more terms.
