Hi,

parabola that has vertex (1,2) and y-intercept (0,5)

Sketch IT

the vertex form of a Parabola opening up(a>0) or down(a<0), y=a%28x-h%29%5E2+%2Bk 

where(h,k) is the vertex  and  x = h  is the Line of Symmetry

 y+=+a%28x-1%29%5E2+%2B+2 , 

Using P(0,5)

5 = a(-1)^2 + 2 , 3 = a

 y+=+3%28x-1%29%5E2+%2B+2
