Transformation of Quadratic Functions 1
Move the slider to change the coefficient of x squared.
You can see the effect of this by comparing the blue graph to the graph of x squared which is red.
Use the buttons to show the table and to turn "Trace On" - you will then see copies of the graph as you move the slider.
Examine the values of a times x squared in the table as you move the slider. A common mistake is to multiply x by a first and then square - be careful.
