Answer to Problem 95RE
Explanation of Solution
Given information:
The following data represent average monthly temperatures for phoenix, Arizona.
Calculation:
Here, we know that:
Now, vertical shift will be:
Thus, the data will repeat after
Now, here we will divide
We can observe that the local maxima occur at
Therefore, shift will be:
Now, we will substitute the values in the function:
Hence, the required answer is:
c.
Draw the sinusoidal function
