Graph of quadratic functions
You can change the values of a, b and c by moving the dots on the scroll bar. Explore the changes of the graph when you change the values of a, b and c !
Try to answer the following questions:
Q.1 When the values of c changes while a and b keeps unchanged, describe the change of the graph.
Q.2 When the values of a changes while b and c keeps unchanged, describe the change of the graph.
Q.3 When the values of b changes while a and c keeps unchanged, describe the change of the graph.
