The standard equation of a circle is (x-h)²+(y-k)²=r², (h,k) is the center, r is the radius.
You have the center (0,-8), you need the radius.
the radius is the distance between the center and any point on the circle.
use the distance formula, r=√(2-0)²+(-5-(-8))²=√13
so the equation is x²+(y+8)²=13

The graph shows the function f(x).
Lerok [7]

The equation that represents the given data is  \RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.

<h3>What is a Function ?</h3>

It is a statement where two variables , one dependent and one independent are related.

It is given that

a cube root function goes through (8, 2), has an inflection point at (0, negative 1), and goes through (8, negative 3).

The equation given in the options are

\rm f(x) = -\sqrt[3]{x} \\f(x) = -\sqrt[3]{x-1} \\f(x ) =-\sqrt[3]{-x} -1 \\f(x) = -\sqrt[3]{-x}

The function goes through (8,2)

Substituting the values

f(x) = -2

f(x) = \sqrt[3]{7}

f(x) = -3

f(x) = 2

The equation that represents the given data is

\RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.
