Answer:
f(x) - 3 : the ones that move the graph down
f(x -3) : the ones that move the graph to the RIGHT
Explanation:
graph transformations:
f (x-3):
if the number is inside the "()" sign with the x -> you will have to move the graph sideways (left or right), but it has a little twist: if the number is negative (i.e: f(x)-3), you will move the graph to the right, and if it is positive, you will move it to the left.
f (x) -3:
if the number is outside the "()" -> you will have to move the graph up or down. there is no twist here: if its negative, it goes down, if its positive, it goes up.
hope i could help:)
