What is the frequency of the sinusoidal graph?

.

Step-by-step explanation:

We are given the graph of a sinusoidal function.

From the graph we see that,

The given graph is represented by the function

Now, 'If a function f(x) is of period P, then f(bx) has period '.

So, we get,

As, have period .

Then, have period i.e. .

Since, 'Frequency is the reciprocal of the period',

We have,

Frequency of the given function is .
