See below.

Assuming there are no omitted parentheses in the question, this ia

$y = cos(2x)+4$

Replacing argument $x$ with $bx$ changes the period from $2pi$ to $2pi/b$ , in this case the period will be $pi$

Adding a constant $d$ after the cosine moved the graph up (for positive $d$ ) or down (for negative $d$ ). In this case we shift the graph up $4$ .

graph{cos(2x)+4 [-6.45, 6.034, 0.9, 7.144]}
