Answer:
C and D are unchanged, but E increases.
Step-by-step explanation:
Given equation of circle
x^2+y^2+Cx+Dy+E=0
But we know that general equation of circle is with center at (h,k)
x^2 + y^2 -2hx -2ky + (h^2 + k^2 – r^2) = 0
Comparing both equations we get,
C = -2hx
D = -2ky
As in the given question we are not changing the coordinates of center so C and D will remain unchanged.
It also gives us
E = (h^2 + k^2 – r^2)
Decreasing r means that a lesser quantity will be subtracted from h^2 + k^2 which will increase the value of E.
