(1) The "-1/2" flips the graph vertically and shrinks it by a factor of 1/2.

(2) The "(x+5)" shifts the graph 5 units to the left.

(3) The "+4" shifts the graph up 4 units.

The order of the transformations is the order in which the expression would be evaluated for a given value of x:

parentheses first (shift 5 units left);
multiplication next (flip and shrink vertically);
addition last (shift 4 units up)

Here is a graph showing the incremental transformations:

red: original,
green: translated 5 units left,
blue: flipped and shrunken vertically,
purple: translated 4 units up,
