Two circles are concentric if they have the same center. Which equation represents a circle that is concentric with
the circle shown but has a radius that is twice as large?

A (X - 4)^2 + (-6)^2 = 4
B (X - 4)^2 + (-6)^2 = 16
C (x - 6)^2 + (-4)^2 = 16
D (X - 6)^2 + (y - 4)^2 = 4

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.

answer:

a=9
