| If we put all of
this together we can see the affect of the coefficient of the quadratic term and of the constant term. What happens when a middle term is added? In other words, what affect does "b" have in y = ax2 + bx + c?
Change the values of
a, b, and c in this notebook to explore. |

| In this notebook,
the quadratic equation is given in a different form, the standard form. See the affect h and k have upon the graph. See the affect of "a". Is it the same as above in the first notebook? Can you determine the vertex? |
