Visualization refers to the graphical representation of any function. It is helpful in understanding the nature of the given function and providing better inferences.
Students must be encouraged to learn how to visualize a given function transformation beginning with some elementary functions such as a straight line or a quadratic function later on they should be introduced to some standard graphs of functions. They must be made aware of the benefits of learning to visualize a given function. Certain software can be also used to visualize functions.
