Using sinusoidal function concepts, it is found that the values are A = 2 and D = 2.
<h3>What is a sinusoidal function?</h3>The cosine function, with standard period, is represented by:
In which:
is the amplitude, which is the difference between the largest and smallest value.
- D is the vertical shift, considering that the standard cosine function has range between -A and A.
In this problem, the amplitude is of 4 - 0 = 4, hence:
The standard function has range between -2 and 2, in this problem it is between 0 and 4, hence the vertical shift up is of 2 units, that is, D = 2.
