For example, if you know that the quadratic parent function \(y={{x}^{2}}\) is being transformed 2 units to the right, and 1 unit down, we can create the original t-chart, following by the transformation points on the outside of the original points.
A rational function is basically a division of two polynomial functions. That is, it is a polynomial divided by another polynomial. In formal notation, a rational function would be symbolized like this: Where s(x) and t(x) are polynomial functions, and t(x) can not equal zero.
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.
