Question

What is the period of the graph of y = 5cos(6x – 1) + 3? O A.

Answer 1

Step-by-step explanation:

The coefficent of the x variable is b.

The formula for the period is

$\frac{2\pi}{ |b| }$

Here, b is 6 so we have

$\frac{2\pi}{ |6| } = \frac{\pi}{3}$

So the period is pi/3, or 60 degrees
