23. The equation of the circle C1 is x2+y2+2x−43y+9=0. C2 is a circle with centre (4,−33). If C1 and C2 touch each other at A, which of the following is/are the possible coordinates of A ? A. (0,3) B. (3,23) C. (0,3) or (−2,33) D. (3,23) or (−26,273) 24. It is given that f(x) partly varies directly as x and partly varies inversely as x2. If f(2)=−5 and f(3)=2, then f(1)= (A. −34. B. −16. C. 20 . D. 38 .
