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)

1. vertex = (0,-4), axis of symmetry is x = 4, y-intercept is 7.

 

2. vertex = (2,4), axis of symmetry is x = 3, y-intercept is 8.

 

1. y = 4(x + 3)^2 + 7.

 

2. y = 2(x - 1)^2 - 9.
