A simple way of observing the effect of changing the constants of a quadratic equation.
This is an excellent tool for displaying how changing the constants in a quadratic transforms the graph. What is brilliant is that the equation is already in completed square form so it is very clear exactly what is happening. This is ideal as a demonstration to students, or could be used as a wrap up with students drawing the curve on mini-whiteboards and you checking it on this spreadsheet. Thank you for sharing.
