Question. Which of the following are rational functions?

f (x) = 0

f (x) = (3x-1) / (x^2-4x+5)

f (x) = e^x

f (x) = (sinx) / (cosx)

f (x) = -4x^-3+5x^-1+7-18x^2

f (x) = x^1/2 - x + 8

All polynomials can be thought of as rational functions.

Step-by-step explanation:

rational functions are:

1) f (x) = (3x-1) / (x^2-4x+5)

2) f (x) = -4x^-3+5x^-1+7-18x^2

3) f (x) = 0
