See explanation and graph.

Explanation:

y = csc ( 3theta + pi/2 ) +3, 3theta + pi/2 ne asymptotic kpi,

k = 0, +-1, +-2, +-3, ...

rArr theta ne asymptotic ( 2k - 1 ) pi/6

csc value notin { -1, 1 ). So,

#y notin ( -1 +3, 1 + 3 ) = ( 2, 4 )

Period is the period of sin ( 3theta + pi/2 ) = (2pi)/3

Phase shift = ( - pi/2)/3 = - pi/6

Vertical shift = 3

See graph, depicting all these aspects.
