Answer:
See below.
Step-by-step explanation:
The range of a graph is the span of y-coordinates the graph covers.
From the graph, we can see that the graph covers all y-values between the values of y=-8 and y=7.
Therefore, the range is all of the numbers in between them including them.
In interval notation, this is:
We use brackets instead of parentheses because we include the numbers.
And in set notation, this is:

Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
