As below.

Explanation:

Standard form of tangent function is #y = A tan (Bx - C) + D#

#"Given : " y = 2 tan (3 pi xi) + 4#

#A = 2, B = 3 pi, C = 0, D = 4#

#Amplitude = |A| = "NONE for tangent function"#

#"Period " = pi / |B| = pi/(3pi) = 1/3#

#"Phase Shift " = -C / B = 0 / (3 pi) = 0, " No Phase Shift"##

#"Vertical Shift " = D = 4#
