To get started, lets consider one of the simpler types of functions that youve graphed. The last two easy transformations involve flipping functions upside down flipping them around the xaxis, and mirroring them in the yaxis the first, flipping upside down, is found by taking the negative of the original function.

The term transformation has severalmeanings in mathematics.
For example, vertically shifting by 3 and then vertically stretching by 2 does not create the same graph as vertically stretching by 2 and then vertically shifting by 3, because when we shift first, both the original function and the shift get stretched, while only.

We will be discussing how these function shapes are related to equations, and how changes in those equations effect the shape of the functions. Complete the rows of the table that show transformations of f, and mark any values that are unde ned with an x. The next series related to the polylogarithm functions the dilogarithm and trilogarithm functions, respectively, the alternating zeta function and the riemann zeta function are formulated from the previous negativeorder series results found in the references. Dilations, however, can be tricky to interpret and tricky to graph, especially since several algebra texts do a poor job of describing what these transformations actually do. A codomain of a function is any set containing the range of the function it does not have to equal the range. In this section, we will learn, how to do different types of transformations of functions like translation, stretch, compression and reflection.

Combinations of function transformations the various preceding function transformations can be combined such that more than one of them is applied to a single function simultaneously. Detailed explanations are not included, but specific examples are given based on the following parent functions. Also, how do we use them in real life, so as a real life application. See editing for functions to read or combine image sequences. Transformations of functions in this section, we see how transformations change the shape of the graph of a function. It may mean any change in an equation or expression to simplifyan operation such as computing a derivative or an integral.
