Q. What is the amplitude ofg(x)=−2sin(2πx−3)+5?units
Identify standard form: Identify the standard form of a sine function.The standard form of a sine function is y=Asin(Bx−C)+D, where A is the amplitude, B affects the period, C is the phase shift, and D is the vertical shift.
Compare given function: Compare the given function to the standard form.The given function is g(x)=−2sin(2πx−3)+5. Here, A=−2, B=2π, C=3, and D=5.
Determine amplitude: Determine the amplitude.The amplitude is the absolute value of A. In this case, A=−2, so the amplitude is ∣A∣=∣−2∣=2.
Check for errors: Check for any mathematical errors.There are no mathematical errors in the previous steps.
