Application of Geometric Sketchpad in Quadratic Function

Quadratic function is a very important knowledge point in mathematics, and its function formula is closely related to function image. If the function formula lacks the corresponding function image to assist, it is difficult to see the change of parameters in the function formula.

Without a clear concept of the whole function formula, it is difficult for students to work out the function formula. Therefore, for a function formula, drawing the function image is very important.

In the traditional quadratic function teaching, teachers often draw the function image on the blackboard with chalk, which is difficult to guarantee its accuracy.
