Select the correct answer. which function has a phase shift of to the right? a. b. c. d.

Sagot :

The function y = 2sin has a phase shift of pi/2 to the right (2x - pi).

What is a trigonometric function?

  • An angle or angle function (such as the sine, cosine, tangent, cotangent, secant, or cosecant) is most simply defined in terms of the ratios of pairs of sides of a right-angled triangle.
  • The inverse of a trigonometric function (such as arcsine, arccosine, or arctangent).

To find the function which has a phase shift to the right:

The function has a phase shift of pi/2 to the right.

By definition, you have the phase shift is:

  • asin(bx+c)
  • Phase shift = -c/b

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

  • Phase shift = [tex]-(-\pi )/2[/tex]
  • Phase shift = [tex]\pi /2[/tex]

Therefore, the function y = 2sin has a phase shift of pi/2 to the right (2x-pi).
