Which equation represents a circle with a center at (2,-8) and a radius of 11

The equation of circle can be determine by using general equation of circle.

The equation for circle would be .

Given:

The center of circle is .

The radius is .

Write the general equation of circle.

Where, is center of circle and is the radius of the circle.

Substitute for , for and for in above equation.

Thus, the equation for circle would be .

(x - 2)² + (y + 8)² = 121

Step-by-step explanation:

circle: (x – h)² + (y – k)² = r²   (h , k) center        r: radius

h = 2          k = - 8          r = 11

equation: (x - 2)² + (y + 8)² = 121

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
