Answer:
A and D should be checked.
Step-by-step explanation:
The first one.
It's center is (-12, - 9) and it has a radius of sqrt(9) = 3 The 12 on the x axis will guarantee that the most in either direction in the x direction is (-15,-9) going left from the center and (-9,-9) going right of the center point.
The two points for up and down are (-12, -12) and (-12,-6)
A graph is included below. The red circle is shown as being entirely in quad 3. It is red in color. It should be checked.
B is Blue and it is shown to be 1/2 in quad 3
C is in green. It is 3/4 in quad 3, but not all of it is there.
D is dark blue and it is quad 3 so it should be checked.
