This graph slides the graph of y = tan x, pi/2 units to the left.
There would be vertical asymptotes at x=0 and x = pi
At x = pi/2 you would be evaluating tan(pi/2 + pi/2 ) = tan(pi) = 0 (pt cross x axis)
Two easy points to graph would be to find the x's that causes x + pi/2 to be 3pi/4 and 5pi/4
So
When x = pi/4 , pi/4 + pi/2 = 3pi/4 thus tan(3pi/4) = -1 times -3/2 would = 3/2
When x= 3pi/4 , pi/4 + pi/2 = 5pi/4 thus tan(5pi.4) = 1 times -3/2 would be -3/2
Three points
(pi/4, 3/2) (pi/2,0) (3pi/4, -3/2)
