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.
