ANSWER

Vertical shift is 1 unit down.

Maximum value is 3

Minimum value is -5.

Step-by-step explanation

The given function is

$y = 1 + 4( \cos(x) - (1)/(2))$

This is the same as,

$y = 1 + 4\cos(x) - 2$

$y = 4\cos(x) - 1$

The vertical shift is 1 units down.

The maximum value is 4-1=3

The minimum value is -4-1=-5
