Answer:
1
Step-by-step explanation:
A linear equation (degree 1) will have one root. A quadratic equation (degree 2) will have two roots. A cubic equation (degree 3) will have three roots. An nth degree polynomial equation will have n roots.
Domain (2 to 4)
Range (-2 to 8)
It’s not a function because there are three points with the x value of 3.

6=69, 7=69, 8=69
Step-by-step explanation:
72
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
