Answer:
right 3 units
Explanation:
for a translation following f(x-a), the graph is shifted right by 'a' units; so 'a' is added to the x coordinates. so for f(x-3), 3 is added to the x coordinates, meaning that it shifts to the right by 3 units.
for future reference for similar questions:
if it was f(x+a), then it would shift to the left by 'a' units
if it was f(x)+a, then it would shift up by 'a' units
if it was f(x)-a, then it would shift down by 'a' units
if it was -f(x), then it would be reflected on the x axis
if it was f(-x), then it would be reflected on the y axis
hope this helps!
