See graph and explanation.

Explanation:

The period = (2pi)/4 = pi/2

( 2 - y )/2 = sec ( 4x + ( 3pi )/4 ) notin ( -1, 1 )

rArr y notin ( 0, 4 )

The asymptotrd are given by

4 x + (3pi)/4 = ( 2 k+ 1 ) pi/2

rArr x = ( 4 k - 1 )pi/16, k = 0, +-1, +-2, +_3, ...

graph{(cos(4x+(3pi)/4)(1-y/2)-1)(y)(y-4)(x+(pi/16))(x-(3pi)/16) = 0[-3 3 -6 10]}

The not-to-uniform scale graph includes y notin ( 0, 4 ) space

and the two asymptotes near O,

x = - pi/6 and x = (3pi)/16
