The following graph shows at least one complete cycle of the graph of an equation containing a trigonometric
Expert Solution
Step 1
The function is continuous so, it can be modelled using sine or cosine function.
Using sine function:
Let the function be .
The mid-line occurs at as maximum is and minimum is , so, we have .
The height above the mid-line is 3, so, .
Thus, function becomes .
As,
So, function becomes .
As,
Thus, the function becomes .
