The vertex form will be[br][math]a\left(x-h\right)^2+k[/math][br][br]This means the vertex is [b](h,k)[/b], and [b]a [/b]tells you your vertical movement from the vertex.[br][br]Remember "Quadratic Motion"[br]From the vertex,[br]Right 1, means Up 1[br]Right 2, means Up 4,[br]Right 3, means Up 9,[br]Left 1, means Up 1[br]Left 2, means Up 4[br]Left 3, means Up 9[br][br]so long as [b]a [/b]is 1.[br]
