Hi,
How do you find the quadratic function displayed in a graph
for Ex
the vertex form of a Parabola opening up(a>0) or down(a<0)is: 
where(h,k) is the vertex and x = h is the Line of Symmetry
check out vertex: y = a(x-3)^2 +2
check out an easy ordered pair: ex (2,4) to find a = 2
y = 2(x-3)^2 + 2
Same Steps with Parabola opening right or left
the vertex form of a Parabola opening right(a>0) or left(a<0), 
where(h,k) is the vertex and y = k is the Line of Symmetry
