Question

What are the period and phase shift for f(x) = –4 tan(x – π)?

Answer 1

The general form of the equation is
f(x) = Atan(ωx - φ)
comparing with
f(x) = –4 tan(x – π)
w=1
Then, period is equal to:
T=π/w (Because the period of tang is π, no 2π)
T=π/1
T=π
For the phase shift:
phase shift = −π (i.e. shifted π units to left)
