It would be A because....
Given the function below:

To find f(-2), we substitute x = -2 in the equation. Since f(-2) means the value of f(x) at x = -2.

Replace x-term to -2 and evaluate.

Answer
Let me know if you have any doubts!
The equation of a circle is written as (x – h)^2 + (y – k)^2 = r^2
h and k are the center point and r is the radius.
In the given equation h = -6 and k = 7 and r would be the square root of 81, which is 9.
Center (-6,7)
Radius = 9
Answer:
21
Step-by-step explanation:
15/ 5/7 = 21
The best estimate would be 2,000 but, the original answer is 2,023
