In
this present investigation, a new class of bi-univalent functions associated
with quasi-subordination is defined and the bounds on the first two
Taylor-Maclaurin coefficients |a_2| and |a_3|  for functions belonging
to this class are derived. Furthermore, several related classes of functions
are also indicated.
