Multiple Choice

An equation of a parabola $$( x - h ) ^ { 2 } = 4 p ( y - k )$$ is given. Graph the parabola. Identify the vertex and the
focal diameter.
- $$( x + 3 ) ^ { 2 } = - 4 ( y + 4 )$$

A) vertex: $( 3,4 )$ ; focal diameter: 4

B) vertex: $( 3,4 )$ ; focal diameter: 1

C) vertex: $( - 3 , - 4 )$ ; focal diameter: 4

D) vertex: $( - 3 , - 4 )$ ; focal diameter: 1
