Which of these functions, if any, are rational? Properties of Rational Functions Several properties set rational functions apart from other functions. First, rational functions are composed of polynomial functions, and polynomial functions are defined for all real numbers. Should rational functions then...
Check out these additional problems to test your knowledge of rational functions and their holes.Practice Questions 1. What are the holes found in the rational function, $f(x) = \dfrac{-3(x – 2)(x + 1)(x + 4)}{4x^2(x – 2)(x + 1)(x – 4)}$? $\left(-1, \dfrac{9}...
Rational functions are functions that involve a quotient of polynomial expressions. While rationals share many properties with polynomials, there are some unique aspects that arise due to the division of polynomials, such as asymptotes and singularities. Solve rational equations, find roots, graph, con...

Theorem 3: If two functions f and g are continuous on an interval [a, b], then the algebra of functions: f+g, f-g, and fg are continuous on [a, b]. But f/g is continuous on [a, b] given that f/g is NOT zero anywhere in the interval. Theorem 4: A rational function is...
