How geometry artboards Draw two functions with the stroke method

Two times function is a mathematical model describing the law of the objective World movement, in the study of two times function, we have learned to use the stroke method to figure out two functions, in the geometry of the artboard we can also use the stroke method to accurately draw two functions, the following will detail how the geometry of the drawing method to draw two times function.

The following steps are described:

The first step defines three coordinate points

Determine three coordinate points: (2,2), ( -2,2), (1,-1).

The second step is to draw a sketch.

(1) Open the Geometry artboard software, click on the left toolbar "custom Tool"-"function Tool"-"parabola 1 over three points". The planar Cartesian coordinate system is then automatically present, so that we can easily find the coordinate point.

(2) Click on the left toolbar "custom Tools"-"Function Tools"-"parabolic 2 over three points", find three points (2,2), ( -2,2), (1,-1) and click on the coordinate system, and then automatically generate two function images, and display the function parsing in the upper left corner.

Three coordinate points were found in the coordinate system to automatically generate two function images

Third Step image adjustment

(1) Scale adjustment

If you think the axis above the scale is a little more or less, we can find the x-axis near the origin of a unit point, the left mouse button hold and drag left and right to adjust the intensity of the point.

(2) Position adjustment

If you feel you are not satisfied with the position of the axis, you can change the position by holding down the red dot above the origin.

The above to introduce how the geometry of the drawing point method to draw two times the function of the method, the operation is simple, we can be based on the geometry of the tutorial a lot of practice.
