Use the equation d(x) = (x-1)² + 3 to identify the new equation if the graph was shifted UP 2 units.

• d(x) = (x-1)² + 1

• d(x) = (x-1)² + 5

• d(x) = (x+1)² + 3

Use the equation d(x) = (x-1)² + 3 to identify the new equation if the graph was shifted DOWN 2 units.

• d(x) = (x-1)² + 1

• d(x) = (x-1)² + 5

• d(x) = (x-3)² + 3
