g(x) = (1/2) * f(x) + 3

The "1/2" shrinks the graph vertically by a factor of 1/2.
The "+3" shifts the graph up 3 units.

A graph, showing the transformations:

red: f(x) = (3/4)x+2
green: (1/2) * f(x): red, shrunk vertically by a factor of 1/2
blue: (1/2) * f(x) + 3: green, shifted up 3 units



The equation of the new graph is

g(x) = (1/2)(f(x))+3
g(x) = (1/2)((3/4)x+2)+3
g(x) = ((3/8)x+1)+3
g(x) = (3/8)x+4
