The co-ordinates of the focus of the parabola ((x+3)^2=2(y-5) ) is

Options

  1. A( ( -5 2 , 5 ) )
  2. B( (-3, 11 2 ) )
  3. C( (3, -11 2 ) )
  4. D( (0, 1 2 ) )

Correct answer

B. ( (-3, 11 2 ) )

Step-by-step solution

( aligned & (x+3)^2=2(y-5) & Vertex =(-3,5), a= 1 2 & Focus (s)= (-3,5+ 1 2 )= (-3, 11 2 ) aligned ) Hence, option (b) is correct.
