Can someone help me do this?
I need to find the domain of this equation:
x - 3 = 2√11-2x

  • math -

    The domain of x - 3 = 2√11-2x
    is R (real) minus the part where
    (11-2x) is negative, whence
    (11-2x)<0
    =>
    2x>11
    => x> 11/2

    Therefore the required domain is
    (-∞,11/2]
