Question

Which function has a phase shift of π/2 to the right

Answer 1

The answer is the option E, which is: E.)$y = 2sin(2x - \pi )$

The explanation for this answer is shown below:

1. By definition, you have the phase shift is:

$aSin(bx+c)\\ pshift=-c/b$

2. When you substitute the values from the function $y = 2sin(2x -\pi )$, where $c=-\pi$ and $b=2$, you obtain:

$pshift=-(-\pi )/2=\pi /2$

Answer 2

Answer:

Your answer is going to be E.) y = 2sin(2x - pi ).
