Answer 1

Answer:

$D.\ y = 3\sin(2(x + \frac{\pi}{4}))$

Step-by-step explanation:

Given

$A = 3$ --- Amplitude

$C = \frac{\pi}{4}$ --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

$y = A\sin(B(x + C)) + D$

Substitute values for A and C

$y = 3\sin(B(x + \frac{\pi}{4})) + D$

By comparison, only option (D) has the above format where

$y = 3\sin(2(x + \frac{\pi}{4}))$

Hence (D) is correct
