To write a cosine function with the given parameters, we need to consider the following:1. Midline: The midline is the horizontal line that divides the graph of the function into two equal parts. In this case, the midline is
, so the function will have a vertical shift of 3 units.2. Amplitude: The amplitude is the distance between the midline and the maximum or minimum value of the function. In this case, the amplitude is 5, so the function will have a vertical stretch of 5 units.3. Period: The period is the distance between two consecutive points where the function repeats itself. In this case, the period is
, so the function will have a horizontal compression of
.4. Horizontal shift: The horizontal shift moves the graph of the function left or right. In this case, the horizontal shift is
to the right, so the function will have a horizontal shift of
.Using these parameters, we can write the cosine function as:
Simplifying the expression inside the cosine function, we get:
Therefore, the cosine function with the given parameters is:
