Open GeoGebra 3D Calculator on your smartphone/tablet and search for the applet below using following code: #ERUAR Alternatively, you can construct the two functions 'from scratch': start in the Algebra tab and define a slider 'k'. Then simply type in the two equations: and . GeoGebra will generate the functions f(x) and g(x). Play around with slider k and see how accurate your sketches were!
