Question 110007: Ok. so this one is a graph of a positive, even parabola which means it opens up. the vertex is (-1,-2) and one of the points on the parabola is (0,-1). It's telling me to write a quadratic function in vertex form for the parabola. what is vertex form and how do i plug in the coordinates to find it? HELP PLEASE! :]

for a parabola with the vertex at (h,k), y=a(x-h)^2+k

the technique is to plug in h and k; and then use a point on the parabola to find a
