Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is

where
are two x-intercepts.
In your case,

so

To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through

and

17. The vertex form of the parabola equation is

where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so

The vertex is 3 units from the focus, then

The equation of the parabola is
