Segway to Quadratics
Activities: |
Play with the parameters that influence the parabola, find the roots. |
![]() |
Focus of the Parabola - use the mouse to drag the Focus and see the effect on the parabola's curve. |
![]() |
|
Experiment with the effect of coefficient
a on the
parabola. ax2+bx+c ("standard form") |
![]() |
|
ax2+bx+c |
when messing with the
b
of this function, the Min point of the
parabola moves along its own similar
parabola. Use Desmos and your own calculations to figure out what is the formula/function for the trajectory that the Min point incurs during changes to b. Click here for one possible solution. |
