The project demonstrates how the scripts of a line graph in Scratch can be easily adapted to graph a quadratic expression. This project illustrates how easy it is. It is basically the Line A graph at https://scratch.mit.edu/projects/714704365 with two small adaptations. (1) The move units in domain script 2 are reduced from 1 to 0.5 (to allow for a curve rather than a straight line). (2) the 'set y block ' in the f(x) script is changed from linear x+1 to quadratic x² . (optional: It may be necessary to change the max and min values of the domain. In this graph the values are from -3 to 3.).
