Which function's graph has a period of 2?
O
A. y = 3 cos2x
O
B. y = 2 sin 3x
O C. y=co(x-1
O D. y = -4 sin AX

b

Step-by-step explanation:

idk

b

Step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
