All you have to do is create an equation and finding the vertex and x intercept. :_

anonymous · Answer

Here's one for you:
y = x^2 - 8x + 12    This factors as y = (x - 6)(x - 2)
So, x-intercepts are at (6, 0), and (2, 0)
This opens up because the implied "a" value is 1.
It also has the vertex form of y = (x - 4)^2 - 4   so it has a vertex at (4, -4) and it is at this point where the graph and equation has its low-point.
