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
