To state: amplitude, period, phase shift and vertical shift of the function and then sketch its graph.
Answer to Problem 8CFU
Explanation of Solution
Given information:
Calculation:
The equation of cosine function is as follows:
Here
Compare the given equation with equation (1) to get,
Now evaluate the amplitude as shown below.
The period of the function will be evaluated as follows:
The phase shift of the function will be evaluated as follows:
The vertical shift of the function is 5 units downwards i.e.
Thus, the amplitude, period, phase shift and vertical shift of the function is
The graph of the function will be as follows:
