Step-by-step explanation:
The given function is [tex]y=\cos x +3[/tex]
The base function is [tex]y=\cos x[/tex]
The single transformation applied to this function is a vertical upward shift by 3 units.
Therefore the graph of [tex]y=\cos x +3[/tex] is graph of [tex]y=\cos x [/tex] shifted up 3 units.
