Question

what is the horizontal shift of the function y=4sin(2x-pi)
A) pi units to the right
B) pi/2 units to the right
C) pi/3 units to the right
D) pi/4 units to the right

Answer 1

Answer:

B) π/2 units to the right

Explanation:

Function : y = 4sin(2x-π)

Basic's:

f(x) = A * g(Bx - C) + D where C/B is phase shift, D is vertical shift.

For this trigonometric function

Identify: B = 2, C = π, D = 0

Horizontal shift:

• π/2

Vertical shift:

• 0
