What is the frequency of the function f(x)?<br> Express the answer in fraction form.
Reil [10]

Answer:

<u>Frequency = 1/period = \frac{1}{8\pi }</u>

Step-by-step explanation:

The frequency of the sinusoidal function = 1/period

Frequency is how many the function repeats itself per unit if time i.e: per "1"

For the given graph :

\frac{x}{4} =Bx , Where: B = 2π/period

period = 2π/B  ,   B = 1/4 = 0.25

∴ Period = 2π/0.25 = 8π

∴ Frequency = 1/period = \frac{1}{8\pi }
