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.
1 Any Rational Number can be expressed as integer divided by non-zero integer e.g integer/ non-zero integer. 2  Example 4 = 4/1. 3  All terminating decimals are rational. 4  Example 5.125 = 41/8.
