Transformations Of Function Graphs
Gbogbo ọrọ náà
Once you know the graph of a function, you can predict the graph of a whole family of related functions without plotting a single new point. Adding a number to a function slides its graph up; adding a number inside the function slides it sideways. These transformations let you see relationships between graphs at a glance.
In this lesson you will identify and describe the effect on the graph of \(y = f(x)\) of the transformations \(y = f(x) + k\) and \(y = f(x + k)\). One shifts the graph vertically, the other horizontally, and recognizing which is which is the heart of the topic.
