Solution

Solution:

y = tan (x + pi/2)

In standard form y = a* tan(bx + c) + d

a = 1, b = 1, c = pi/2 and d = 0

Period T = pi/b = pi/1 = pi

So period is pi radians or 180 degree

Undefined Values;

tan(x+pi/2) = sin(x+pi/2)/cos(x+pi/2)

---> cos(x+pi/2) = - sin(x) = 0 ---> x = pi*n

Undefined Values: -2pi, -pi, 0, pi, 2pi, etc...

So graph is bottom left side i.e. (c)
