Answer:

#color(purple)(Amplitude = 2, "Period " = (2pi)/3#

Explanation:

#y = A sin (Bx - C) + D# is the standard form

#"Given : " y = 2 sin (3x + 3* 30') + 4#

#90' = 1.5^@ = (1.5 * pi) / 180 = 0.0262^c#

#y = 2 sin(3x + 0.0262) + 4#

#A = 2, B = 3, C = -0.0262, D = 4#

#Amplitude = |A| = 2#

#"Period " = (2pi) / |B| = (2pi) / 3#

#"Phase Shift " = C / B = -0.0262/3 = -0.00873#

#"Vertical Shift " = D = 4#

graph{2 sin (3x -0.00873) + 4 [-10, 10, -5, 5]}
