Final answer:
The period of the given function f(t) = -3 tan(2x) is π/2.
Step-by-step explanation:
The given function is f(t) = -3 tan(2x).
To determine the period, we need to find the value of x that results in the same value for f(t) as for f(t + T), where T is the period.
For the tangent function, the period is π/2, so the correct answer is A) π/2.
