<h3>How to graph the function?</h3>The equation of the cosine function is given as:
f(x) = cos(x) - 3
The above function is a cosine function, and the parent function of the cosine function is
f(x) = cos(x)
This means that the function f(x) = cos(x) is translated 3 units down to get the function f(x) = cos(x) -3
Next, we plot the graph of the function f(x) = cos(x) - 3
