Question

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

1. Period: π; phase shift: x = check Correct
2. Period: π; phase shift: x = π
3. Period: 2π; phase shift: x = close Incorrect
4. Period: 2π; phase shift: x = π

Answer 1

2

Explanation:

Period of tan is π radians

f(x - π) is a horizontal shift of π towards the right
