Parabola investigation

Investigate the significance of the coefficients a, b and c in the quadratic function

1. Drag the c slider. How does it change the graph? Can c be found somewhere on the graph? Try with different values of a and b. 2. Drag the a slider. How does it change the graph? Is there a pattern in how a changes the graph? Try with different values of b and c. 3. Turn on the tangent (tick mark) Drag the b slider. What happens? Find the connection to the tangent slope.
