Identify the vertex, axis of symmetry, and y-intercept. Graph the function.
1. y=-6(x+4)^2 -3
2. y=1/3(x-1)^2 +3
Write a quadratic function in vertex form whose graph has given vertex and passes through the given point.
1. vertex (-3,5); passes through (0,-14)
2. vertex (1,8); passes through (3,12)
