- Getting to know different type of functions and approximation of lines and curves in real life objects -> go there
- Quadratic functions, root functions and power function y=ax^n are used to create these wonderful pictures! (see original pictures here) GeoGebra command function(x^2+1,-2,3) draws f(x)=x^2 from x=- 2 until x=3
