Respuesta :

f(x) = 5tan(2x - pi)
first the 2 must be factored out of the parenthesis.
f(x) = 5 tan 2(x - pi/2)
The period for tangent is pi/k. In this equation, k = 2
so the period is pi/2.
The phase shift is also pi/2 because of the pi/2 that is in the parenthesis.

Hope this helps!

The phase shift is pi/2, but the period is is 2pi over the absolute value of b so it should be 2pi/2 which equals pi
