Find Amplitude, Period, and Phase Shift f(x)=2sin(3x)

Problem

ƒ(x)=2*sin(3*x)

Solution

  1. Identify the standard form of the trigonometric function, which is ƒ(x)=A*sin(B*(x−C))+D

  2. Determine the amplitude by taking the absolute value of the coefficient A

|A|=|2|=2

  1. Calculate the period using the formula P=(2*π)/B where B=3

P=(2*π)/3

  1. Find the phase shift by identifying the horizontal displacement C Since there is no value subtracted from x inside the sine function, C=0

Phase Shift=0

Final Answer

Amplitude=2,Period=(2*π)/3,Phase Shift=0
