The function f(x) = 3 tan(2x) - 3 is graphed on a radian x-axis. Which description correctly identifies its key tangent features? Let n be any integer.
A
Period π; zeros x = π/8 + n(π); vertical asymptotes x = π/4 + n(π); branches increase on each interval between adjacent asymptotes.
B
Period π/2; zeros x = π/8 + n(π/2); vertical asymptotes x = π/4 + n(π/2); branches increase on each interval between adjacent asymptotes.
C
Period π/2; zeros x = π/8 + n(π/2); vertical asymptotes x = π/4 + n(π/2); branches decrease on each interval between adjacent asymptotes.
D
Period π/2; zeros x = π/4 + n(π/2); vertical asymptotes x = π/8 + n(π/2); branches increase on each interval between adjacent asymptotes.
