Writing Equations in Vertex Form:
2
general equation
y = a(x h)
+ k
where: (h, k) are the coordinates of the VERTEX
"a" determines direction of OPENING
whether STRETCHED or COMPRESSED
2
To determine "a" the coefficient of the x
term...
1) first step of the Step Pattern from the Vertex
2) if the first step is difficult to determine,substitute a point
from the graph into the general equation in vertex form, and
solve for "a"
