The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real n
umbers. The range is {y|y < 16}. The domain is all real numbers. The range is {y|y ≤ 16}. The domain is {x|–5 < x < 3}. The range is {y|y < 16}. The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}.

Answer:
The domain is all real numbers. The range is {y|y ≤ 16}
Step-by-step explanation:
we have
This is a the equation of a vertical parabola open downward
The vertex is a maximum
The vertex is the point (-1,16)
see the attached figure
therefore
The domain of the function is all real numbers ----> interval (-∞,∞)
Te range of the function is
All real numbers less than or equal to 16 ----> interval (-∞,16]

The length of the AB is 22 units if the length of AC is 44 units and DB is the median of the triangle.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
The figure is missing.
The figure is attached to the picture, please refer to the picture.
We have a triangle shown in the picture.
As we know, the median bisects the side length into two equal parts.
AB = AC/2
AC = 44 units
AB = 44/2
AB = 22 units
Thus, the length of the AB is 22 units if the length of AC is 44 units and DB is the median of the triangle.
