Some Real-Life Applications of. Rational Functions. There are many situations in the real world where an application of a rational function is used as a representation. There are three well-known situations that follow under this category of rational functions.alculating pH with a logarithmic function. A logarithmic function can be used to calculate the pH of a substance based on the concentration of hydrogen ions. This is the logarithmic equation that is used for determining pH.
Rational Functions In this chapter, youâll learn what a rational function is, and youâll learnhow to sketch the graph of a rational function. Rational functions A rational function is a fraction of polynomials.That is, if p(x)andq(x)are polynomials, thenp(x)q(x)is a rational function. The numerator is p(x)andthedenominator is q(x).Examples.â¢ 3(x5)(x1) â¢ 1x â¢ 2x 3 1 =2x 3 The last example is both a polynomial and a rational function.n a similarway, any polynomial is a rational function.In this class, from this point on, most of the rational functions that weâll seewill have both their numerators and their denominators completely factored.We will also only see examples where the numerator and the denominatorhave no common factors.
