Given:
The sine function is:
To find:
The frequency of the graph of given function.
Solution:
If a sine function is defined as:
Then, the frequency of the sine function is:
We have,
Here, . So, the frequency of the given function is:
Therefore, the correct option is D.
The given equation is
And we have to solve for y.
Solving for y, means isolating y . And to isolate y, we need to get rid of 4 that is with y .
It means we have to separate 4 from y, and for separation , we have to perform division. That is, we have to divide both sides by 4, and that will be the next step .
So out of the four options, correct option is the last option .
