Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
================================================
y = g(x - 4) - 2
shift the graph of g(x) 4 units to the right and 2 units down.
