The correct answer is option (<span>B) Period: π; phase shift: x = π</span>
The equation for finding timeperiod and phase shift is: <span>a tan(bx-c) +d where, a = amplitude Time period = </span>π/b phase shift = c/b therefore, comparing the given equation we get, <span>f(x) = −4 tan(x − π) we get,
thus, answer is time period = </span>π phase shift = π
