To determine which graph shows that \( y = f(x-3) \) is the result of the function \( y = f(x) \) being translated by 3 units to the right, we need to understand how function translations work.

When we have \( y = f(x - c) \), it translates the graph of \( f(x) \) to the right by \( c \) units. In this case, since \( c = 3 \), the graph of \( f(x) \) should shift 3 units to the right.

Look for a graph where the solid graph (translated function) maintains the shape of the dotted graph (original function), but is shifted to the right by 3 units.

Without the images to directly analyze, I can advise you to look for:

  • A graph where the "dotted" line (representing \( f(x) \)) is clearly 3 units to the left of the "solid" line (representing \( f(x-3) \)).

Based on this understanding, choose the option that matches that description.
