The transformation from the equation \( f(x) = x^2 + 1 \) to \( f(x) = (x - 3)^2 + 1 \) involves a horizontal shift.

Specifically:

  • The expression \((x - 3)\) indicates a shift to the right by 3 units.
  • The "+1" at the end does not affect the horizontal transformation and simply indicates a vertical shift up by 1 unit.

However, the problem only asks about the horizontal transformation.

Therefore, the correct answer is:

The graphed function would shift 3 units to the right but otherwise have the same shape.
