A rational function is a ratio of polynomials where the polynomial in the denominator shouldn’t be equal to zero. Isn’t it resembling the definition of a rational number (which is of the form p/q, where q ≠ 0)? Did you know Rational functions find application in different fields in our day-to-day life? Not only do they describe the relationship between speed, distance, and time, but also are widely used in the medical and engineering industry.
Let us learn more about rational functions along with how to graph it, its domain, range, asymptotes, etc along with solved examples.
