Function transformations refer to how the graphs of functions move/resize/reflect according to the equation of the function. Learn the types of transformations of functions such as translation, dilation, and reflection along with more examples.
One simple kind of transformation involves shifting the entire graph of a function up, down, right, or left. The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function.
Function Transformations. Just like Transformations in Geometry, we can move and resize the graphs of functions. Let us start with a function, in this case it is f (x) = x2, but it could be anything: f (x) = x2. Here are some simple things we can do to move or scale it on the graph: We can move it up or down by adding a constant to the y-value:
Rules of transformations help in transforming the given function horizontally or vertically by changing the domain and range values of the function. Let us learn more about the rules of transformations, with graphical representations, and examples.
When the graph of a function is changed in appearance and/or location we call it a transformation. There are two types of transformations. A rigid transformation 57 changes the location of the function in a coordinate plane, but leaves the size and shape of the graph unchanged.
Solution. Begin with the squaring function and then identify the transformations starting with any reflections. y = x2 Basicfunction. y = − x2 Relfectionaboutthex − axis. y = − (x + 5)2 Horizontalshiftleft5units. y = − (x + 5)2 + 3 Verticalshiftup3units. Use these translations to sketch the graph.
Function transformations describe how a function can shift, reflect, stretch, and compress. Generally, all transformations can be modeled by the expression: af (b (x+c))+d. Replacing a, b, c, or d will result in a transformation of that function.

Transformations of Functions. Objective 1: Using Vertical Shifts to Graph Functions. Let c be a positive real number. The graph of units. = f ( x ) + c is obtained by shifting the graph of y = f ( x ) vertically upward c. = f ( x ) − c is obtained by shifting the graph of y = f ( x ) vertically downward. units.
