Question

Question 5 of 30 What is the period of the graph of y 5cos(4x – 1) + 3?

Answer 1

Answer:

Period is $\frac{\pi}{2}$

Step-by-step explanation:

For the function $y=acos(bx-c)+d$, the period is $\frac{2\pi}{|b|}$.

Therefore, the period of the function is $\frac{2\pi}{|b|}=\frac{2\pi}{|4|}=\frac{2\pi}{4}=\frac{\pi}{2}$.

What this means is that the function's wave cycle will repeat every $\frac{\pi}{2}$ units.
