Answer:
|a| is the vertical stretch factor. If a is negative, there is a vertical reflection and the parabola will open downwards.
k is the vertical translation.
h is the horizontal translation.
Step-by-step explanation:
Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.
