In which direction must the graph f(x)=x be shifted to produce the graph of g(x)=x-14

To move  a funciton c units up, add c to whole function
to move a function c units right, minus c from every x

we can do
f(x)-14=x-14=g(x)
it could be shifted down 14 units
or

f(x-14)=(x-14)=g(x)
shifted right 14 units
can be right or down

The answer is all about the number 4
